Is Bluetooth going to be the technology that never was ? - General Topics

There are loads of major manufacturers all planning to launch Wireless USB devices later this year.
Intel have thrown themselves heavily behind this new standard, or rather this extension of the existing USB standard. USB is already the most popular and pervasive interface in the world.
Who thinks this will kill Bluetooth ?
Personally I can't see bluetooth lasting for long once there is an alternative that actually works properly. It's hard to think of another technology that has promised so much and delivered so little and been so full of bugs, glitches, incompatibilities etc.
I think the Wireless USB will appear, having learnt from all of Bluetooth's ghastly mistakes, and take the industry by storm. Bye bye bluetooth.

My last three phones were bluetooth, my last two handhelds, my curent phone/handheld, my gps, my PC, all my current gear works as expected.
What was your point again?

Read this and many other forums on bluetooth related topics.
All you read is problems with pairing, problems with sound quality, problems with compatibility, dopped connections, things either not working they way they should or not working at all.
Bluetooth, in general, is flaky.

Wireless USB isn't even here yet, thus hasn't been tested properly yet, and you're sounding the death knells of BT.... you're certainly an optimist!

I also have no problems with bluetooth; certainly no more than I do with USB devices any way.

For one thing, in the very begining, people were saying that BlueTooth doesn't stand a chance because of it's short 10 meter radius. Well have you seen an 802.11b Wi-Fi headset? If there is I bet it costs a lot.
Everyone was skeptical but look at how technology is with regards to the phones, having BlueTooth is important when selecting a phone. Transfering small pictures, having printouts or even on your BT headsets. Wifi coss too much and I think Bluetooth will evolve into something that IR could not.
In my opinion it will stay for the next 5 years and then a better version will be out.

Don't get me wrong.
I'm not against BlueTooth.
I think bluetooth is quite well conceived as a technology, but disasterously implemented by a lot of manufacturers.
I understand and agree with the points made about the usefulness of short-range wireless and personal area networks etc etc. I think there's a great future in it.
My point is, that Wireless USB is quite clearly going to be stepping on BlueTooth's toes in a way that Wifi does not. We've seen it happen in the past with other standards like Betamax and VHS, even ethernet and token ring (although token ring still exists in various forms).
I'm not sure the various industries will stand for two such similar technologies and the way the players are lining up at the moment I think WUSB will have the edge.

Slot in Bluetooth headset

Just a thought - has any manufacturer sold a phone/pda with a "built in" bluetooth headset?
Was just thinking about it and I reckon it would certainly be feasible (but would need clever marketing).
take a phone, especially one the size of a PDA and where the earpiece is, you have a slide out, narrow/thin format BT headset.
When in the phone/pda the headset is powered and directly connected to the device, adnd thus acts just like a normal earpiece within the phone.
When out of the phone, it's powered by an internal battery (charged from the phone), and acts just like a normal, simple, headset. The act of pulling the headset out of it's slot could also be the signal for answering a call, turning on voice dialling or whatever (software setable), and vice versa.
Obviously there'd be some drawbacks - short battery life (can be lived with/improved over time), the phone/pda would need sufficient depth (shouldn't really be an issue), and it's added complexity and cost. But if it was suitably well designed and marketed I think there's a market out there.
I for one find it very annoying that the greatest use of the phone/pda, namely having a diary/mini PC, and a phone in one device, is destroyed in one instant by the realisation that you can't use it in both ways at once, UNLESS you buy a seperate item, or use the wired earpiece (irritating).
Also BT headsets are even smaller than phones ever were and are prone to being mislaid, damaged etc very easily - by storing it in the phone body you have a safeguard.
I think I saw a concept design of a phone for children that had this feature, although I've thought of it before now, but it's good that it's occurred to someone else! (prooves I'm not totally mad!)
Any opinions?
Disposable sticker headset? Pre-charged, used as a tatoo on one side of the face?

Android In-Vehicle Infotainment

So I've had a project for the last few months getting Android running as an infotainment system. Here is a demo i thought i'd share with you guys..
http://www.youtube.com/watch?v=fNcDq9S8n3I
Basic features:
Android 2.1 (looking to update to GB)
7inch touch-screen (800x480)
3G modem
GPS
Reverse camera (backup camera to see what's behind you)
USB port
would love to hear some criticism or anything regarding the device.. its not perfect, its got a few bugs and glitches.. but is sort of ready for everyday use but is missing a few components to make it 'official' android device (wifi, bluetooth etc).. but i'm just wondering if anyone is interested in something like this? Is this worth developing further on?
This thing runs on Cortex a8 omap3530 board and is based off 0xdroid build.
apologies if im in the wrong forum
Wow dude, thats really cool! I'd love one of these for my car. If you could get Honeycomb on that bad boy it'd be sweet! Just wondering, how do you plan on setting up a rear view camera? Just connect a camera at the back of the car to the tablet itself, then run the Camera app? Seems like the simplest way to me..
Haha cheers love to see the honeycomb source once its out then we'll talk although I'd imagine i'd need better hardware...
currently camera is interfaced by usb (has a usb hub) so i got a cable running under the carpet through the boot then camera is mounted on the bumper. yup camera is called by any camera calling intent.. so any app can use it.
I want to get some proximity sensors (like parking sensors) and write a proper reverse cam app to complement it. But we'll see...
Very cool!
I've been wanting to do this for a while, but I was going to use MeeGo or maybe Moblin since I don't have the programming skills (or Android knowledge for that matter) to build my own computer around Android. I dig what you got so far though.
My suggestion for the reverse camera is one of two things, because it would bug me to have to find and open the camera app every time I needed to back up.
Keep your touchscreen (what model are you using BTW?) and use a bluetooth or wi-fi relay (I know they make 'em, but they are $$$) to provide an input from +12V signal from your reverse light wire to automatically open the camera app, then close the app. Of course, you'd have to program for that.
Or
Have you considered this touch screen? Lilliput 7" touch screen with auto-reverse input. (Needs a RCA camera though)
http://store.mp3car.com/Lilliput_629GL_70NP_C_T_7_VGA_Touchscreen_w_Aut_p/MON-016-0002.htm
This is the one I plan on using since it switches automatically to the camera input whenever you are in reverse. Once you go back to any other gear, the OS input shows up again.
Just a thought to make life a little more convenient (although you already bought your parts so you may be stuck.)

Thanks a lot! It needs a lot of time and dedication but it's a real good learning curve. I had to learn a lot of things on the way.. especially c/c++ I wasn't great at but had decent skills with higher level programming.
If you are planning to work with MeeGo its a little fussy with the hardware requirements.. Correct me if i'm wrong, but I think you need an Intel Atom processor. These are a little pricey if you're after an evaluation/hackable kit! But I'd imagine it'll be easier to program as it's a lot more closey coupled with linux.

I just had a look at those relays, sounds like its something I really need! Is this how the standard backup cameras work? That was something I was confused about.. I wasn't sure how to detect if i'm on reverse.. especially with the parts I already had. I'd imagine once you implement it you just need a service running in the background to listen for the relay.
The touchscreen is a TFT resistive 4wire touch-screen. It's not something I want to keep as I really want capacitive multi-touch.. But this fits perfectly with the board and was easier to deal with

I think most factory backup cameras use two inputs and switch between them. I don't have a lot of experience with them though.

Not sure what you mean exactly. I'll try the relays because it at-least gives me a standard interface to work with (bluetooth or wifi) so there isn't any work you have to deal with on the hardware abstraction.. Although it would probably be better designed if I had some sort of voltage input coming when the vehicle on reverse (the reverse light as mentioned). But I don't really have the electrical expertise to make it happen lol.

Well essentially what I was thinking was you'd have the bluetooth relay hooked up to your reverse light wire. This should allow your computer to monitor whether or not your car was in reverse. Relays are pretty simple - one input switches on/off another, usually one of a much higher or lower voltage. So in essence, it's a switch activated by voltage. (There used to be an electromagnet inside that physically moves a piece of metal to make a connection when a voltage is applied - now it's all transistors and whatnot.)
So, if you are in reverse and your reverse lights are getting power, the bluetooth relay should sense that and signal the computer (through a serial command it seems) which in turn could tell a background service to open the camera app. Once the voltage from the reverse light wire is lost, the relay should again tell the computer that you aren't in reverse anymore and the background service would close the camera app and re-open whatever app you were in.
*I should note this is all "in theory"... I don't know exactly how those wireless relays work/communicate and I don't know Android programming at all.
Thanks for the feedback. I was thinking what about using the GPIOs on the board and attach that to the reverse light? would that be possible? and using some resistors on the way to limit the voltages so i don't fry the board.. but we just need to detect some voltage input...
Not sure, will look into it. Right now, taking a pause on the development.. Got a lot of work to take care of but I can't wait to get back into it. I really want to port this to gingerbread.

You could possibly do that, a real cheap voltage regulator would probably be better though. You could also use a cheap relay if the correct voltage is already somewhere on the car. Again, I'm not too sure how those bluetooth relays work, but it sounds like you are on the right track.
Great Job!
I was thinking of doing something similar myself.
I am looking at going with one of the tablets as it is just seems easier? I only really need internet, google maps(GPS) and wifi tethering. I would imagine you are running stereo sound from a 3.5mm? I would still have a seperate head unit to control volume and handle all the regular functions as well as inputs from a 3.5 to RCA cable.
How are you running sound off that setup? Are you running a head unit still?
The sound is running off a small amplifier. then RCA to 3.5mm.
Haven't had the chance to play around with the wifi tether as right now i don't have a wifi card.. It would make sense to have wifi tethering or just wifi reciever and use a phone to tether 3g to the system. Avoids having separate data plans.
Can we get a copy of your "AIVI Car Home" for our own DIY projects?
I don't mind releasing the source for it. Its just right now its a bit messy and quite a few things are hardcoded.

Nice project. I gutted a Clarion Mind last year to do pretty much the same thing but am looking to upgrade. You said the software needs work but it's a real good start. Would you mind sharing your hardware list with us?
Nice work!
Something I was also interested in seeing is having vehicle manufacturer recommended service intervals and such available as reminders from your in car system or phone or both.

You could use 'aCar' which, if you are unfamiliar, you enter the make, model, mileage and all the pertinent service requirements. Battery every 3 years or 50,000 miles, coolant every year or 15,000 miles, oil every 6 months or 3,000 miles, etc. Then, every time you get gas you enter the current mileage as well as gallons/liters of fuel and the price. From that information you not only get your MPG but it will also trigger reminders to do the necessary maintenance at the correct intervals when they come up. You can do this for multiple cars as well. It's a very good program.
On a related note to this thread, I started my own 'carputer' project using an Archos 70 Internet Tablet and an unused articulating wall mount for TVs. It's still a work in progress as well since I don't have all the parts yet but will do everything I wanted (eventually... lol) except the rear facing camera. The video is obviously just of the media player.
I shot this late last night to show a friend. He wanted to know why someone would want a tablet/computer in their car, lol. Sorry about it being so dark.
Dude
I am keen as mustard on one of these beauties, I was considering running xp MCE but the android option would be much nicer..
Love ya work.

Droid Charge hardware upgrade

So, a coworker pointed me at a chrome book, and said, "Look, it's awesome, 10+ hours battery!" I was skeptical, I've heard horrendous things about chromebooks' usefulness, but then I found out chromebooks give you access to TTY, so in theory you can use all the nifty CLI utilities that make Linux/Unix systems so great to work with. So I went back and reexamined how I use my endless supply of various devices, from desktop to mobile phone. For the most part, I use my phone to call, stream, or browse. I use my laptop to connect to my development machine (It's just inconvenient to hold my code on my local machine for a variety of reasons, and it's not really safe practice anyways.) A short while ago, I was looking for a tablet with a data plan, and I couldn't find one - even carriers with unlimited data plans don't support tablets with unlimited data plans. Damn it! Then, as I was researching chromebooks, I realized something spectacular - despite tablets having a thicker, and therefore heaver screens, tablets are in general 1/2 the weight of chromebooks. (wtf?) So I went in search of system on a board computers, and I found MK802, which could cover all the essentials - a keyboard w/ trackpad, wifi, bluetooth, audio, video. But then I realised - I've got a heap of old android devices from the G1 all the way up to my most recent (but still outdated) Samsung I515 (whatever that's called in common-folk-tongue). And I thought to myself, "Why not use the PCB out of one of those old, working-but-outdated phones to make a DIY tablet or chromebook which will probably weigh less than COTS chromebooks, register as a cellphone with the carriers, have unlimited LTE data, and 20hr battery life?" The Droid Charge seemed like the best candidate. Although I have a couple extra I515s, the awesome thing about the Droid Charge is that it has an HDMI port. Work on the fly, come home, hook it up to a proper monitor, instant win!
Unfortunately, I haven't ever worked with drivers, firmware or the likes. I could probably MacGyver a way to hook up a keyboard with a touchpad to use the micro usb jack (I mean I'd just need to emulate hooking the DC to a dock, right?), but the real blocker for me would be the screen. I imagine there MUST be a way to swap the stock LCD and touch screen digitizer on the Droid Charge, and hook up a 10-12in one, probably from some other Samsung product, but that's completely speculation. I was hoping someone on here could help me out with hashing out how to do the screen swap up to a 10-12in screen.
Thanks,
Misha

General IDOING UIS7862 with WRX[Updated with initial review]

After a lot of reviews and reading I just ordered a 9" Idoing with CanBus for my 2018 WRX with Harman Kardon. A lot of positive reviews from WRX owners, but not seeing a lot of love(or hate) for the Idoing hear on XDA. It's nearly identical to the Joying, but Joying will not support the HK system in my car.
The system is an android 10, UIS 7862 4+64. https://www.aliexpress.com/item/32955093508.html
I'm curious what custom options I have in terms of UI, ROMs, Root,, apps?
I'm guessing from what I read(or lack there of) ROMs are a no go, but what about root and other customization options?
Sorry long time rooter and custom ROM user for android phones and tablets, but total noob to android head units.
I have a Kenwood with wireless android auto in my old car and was going to move it to this one, but absolutely hate Android Auto almost as much as I hate mirrorlink in the stock HU in my WRX(shame on you subaru). Also the kit to install it from crutchfield cost nearly as much as the android unit and canbus shipped from china, so figured i'd take a chance.
If it doesn't work out I'll go with the kenwood, but really hopeful this will be a winner. I spent a lot of time on chat with them and they are extremely responsive to questions(really like live chat) where a question to Joying took 3 days to get a response.
I know there is little chance the 4G module will work in the US(IDoing says it works with tmobile) so expecting to use wifi tether with my phone with native apps and pretend android auto doesn't exist. Other option is put a spare phone with sim permanently connected to USB, but unsure if USB tether will work.
I will keep reading, but any thoughts or pointers are welcome. Just don't tell me to replace my HK system, I know not everyone likes it, but I love it ;-)
FAIR WARNING!!!! After a year with no issue, My IDoing fried itself today!! I was driving and it shut down and for about 1 minute I could smell burnt electronics. This was a plug n play install so no cutting, no splicing, no soldering. I am in the process of seeing what IDoing will do for me, but I expect the answer is nothing since it is now over a year old.
Update: Well at least IDoing is talking to me. I pulled the unit out today and put the Stock stereo back in(UGGGH). At least nothing else got fried.
Update 2: So they are saying that they want me to pull the unit off the mounting trim and mail it to them and they will send me a knew one. I'm assuming this is going to cost me 100 bucks in shipping and need to wait a month or more, but it's better response than I expect.
Update 3: They "say" that once I give them tracking number for the unit, they will ship new unit and all i have to pay for is return shipping(30 dollars)
Final Update: Well it cost me a lot more than the USPS web site inferred (85 dollars), but they shipped a replacement the same day I gave them the tracking for the return. New unit showed up in just over a week, Unit looks new installed in less than an hour and all works great, software looks to be nearly identical except the AA software that it came with support wireless out of the box, so small bons. Unfortunate the original unit fried itself after a year, but considering it was out of warranty I have to commend Idoing on how they handled this, now I just need to remember all the tweaks I had installed ;-)
Roms, you have 2 options both are "Lite" versions meaning you have to buy the other features.
No real need for twrp.
Best bet make sure it works with Android auto wireless
Also pay close attention to the button layouts for the different types of screens.
Most development will be in the "Android auto" fourm
Also ask the seller to provided the zlink activation codes
Hmm, I'm curious why I would use AA at all with this as opposed to running apps on the unit with wifi tether? I've used AA Mirror in the past with my kenwood, but would prefer to avoid that path if possible.
It should work with AA, but not wireless as far as I know.
So my unit arrived today:
https://www.aliexpress.com/item/32955093508.html
Got it to the point of plugging it in to test in the car.
Adding Heating controls vents was a Piece of Cake and this thing looks amazing
Tested:
Screen: Fast and gorgeous responsive, seems very good in bright sunlight
capacitive buttons:, work well , Reset and reprogrammed and much better. Also Illumination is working with custom colors.
Well Documented low volume buzz... Yep it's there, goes away if you mute the radio. Will look for setting to reduce perhaps as well as talk to IDoing
Harman Kardon Canbus, Works plug and play. One issue that may be related is the Fade controls don't really work to fade to rear as they mute the rear, while balance controls work fine... Talking to IDoing now and they just confirmed that any factory amp radio has this issue.
Wifi 5ghz tether, works flawlessly, get 50mbit off my cell. Not the fastest but more than good enough
Play store/google account setup: works flawlessly. Have installed several apps already
Waze/GPS: works flawlessly
USB: 3 dongles, all work for USB Drives, haven't tested for phone connection
Flac: Works off all 3 usb(one main reason I went with this unit)
4g: Working well with t-mobile, not working with verizon. Verizon shows as full bars, bars when I went more urban, but there are no APN settings and I cant get data to work.
Bluetooth audio: works ok, sound doesn't seem fantastic, but i will probably never use.
Android Auto: Wired works great, can't get wireless to work even though my phone says the head unit supports it. Wired it's very fast and responsive and looks great.
Carplay: works wired and woreless, didn't test much as I don't use apple except for app testing.
Fubo/Video: Works very well screen is gorgeous
Developer options: IDoing gave me codes
Launcher: Pretty flexible with different options.
Got USB Debugging, ADB to work today. In developer setting there is 3 "..." at the top, in there is USB mode, top is host mode, bottom is device mode(ADB).
Once I got ADB going I got SystemUITuner granted permissions to control immersive mode for Waze and the like.
Custom Launcher: Got custom launchers working with a trick to use the setting in Nova to set default launcher. Now Rocking Car Web Guru launcher. Also Like Car Launcher Free Version.
Split screen : woks well and is even remembered as last view on soft boot.
Geekbench: 500+, 1300+ very pleased.
android auto with Head unit reloaded: tested with dev server method. Works well with wireless, but UI layout is pretty bad.
Console USB Adapter: Bought from amazon, works perfectly. Now 4 functioning USB
USB access for File Manager : doesn't work yet
Music Apps: do have access to USB
Automation: Used Macrodroid to start Android auto whenever the phone usb is plugged in, or to start spotifiy if no usb and wifi connects. Will do some more of these.
Overall:
Bummed about the rear speaker control, will have to see how much it affects my listening, found subwoofer control an tweaked EQ, sound is quite nice, still wish fade worked. Ok next note to others, make sure you calibrate your EQ with your back seats up. I forgot I had put them down to get my bike in and that was half my disappointment with the sound. Yes I still wish I had fade, but this thing sounds Really nice once dialed in.
The buzz is "irritating" that it exists, but unlikely a real issue for me.. Totally inaudible when car is running.
Otherwise this thing is pretty sweet so far.
Hi gottahavit,
I was just looking at this model on aliexpress and this post comes in just in time as you would say. I have a 2017 STI with no HK
What is your experience with the Mic for calls? does it retain the factory mic or do we have to plug in a new one?
You mention codes for Dev, can you share these?
The console USB Adapter - Which one did you use? do you have a link?
Have you tested ODB2 with apps like Torque?
The External GPS antenna is it required for it to work?
What about the 4G antennas?
thanks so much!

So first, IDoing have been fantastic in helping with the right purchase and the support, but that said this suffers from a lot of issues the other MFG units do. If you had HK I'd def recommend the IDoing as it's plug and play works great.
However if you don't have the HK I might suggest you get a version with optical or coax out. I think Joying and Daisata sell the same unit but with one or the other cabling.
I don't really make calls, but have tested a couple and was told the mic is ok. No you can't keep the stock mic or GPS.
Codes:3368 for factory, 7171 for Launchers
USB: https://www.amazon.com/gp/product/B01DJ4KVQ6/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1 works perfectly.
No ODB2 here, should be the same as the Joying in another thread.
You need the GPS if you want waze or maps on the unit vs AA or Carplay. I just mounted it on the top of the unit and it works great.
4G works fine with Tmobile, I tested with a Mint mobile trial, but cannot get proper APNs in for Verizon SIm to work(still on my hit list)
I recommend the coax as so many of these unit suffer from some form of ground loop interference which is just annoying even if it doesn't really affect the sound. I had no choice given the HK system
Even with the HK this thing cranks our a lot more power than the POS subaru unit..
These things are great and all the work of install is getting the old unit out. It's not perfect but leaps and bounds above stock.
The other reason to go with Joying is you'll get more support here than you will with the IDoing(very specialized to subaru).
If you do buy from IDoing just chat with them first they will help you pick the proper unit and any canbus for your car.
I would definitely go with the UIS7862 version, as this thing is fast!
Thanks for all the information! Really clarifies what i need to get. Ill look at the joying unit and see what the differences are... There was also the Teyes CC3, but man is it more expensive but looks absolutely awesome

Looking I see the unit 6+128 would be cool, but be careful, they all say forrester and have foreester button config for the top lcd and 4-wasy buttons. Maybe they have insert for WRX like IDoing. Also I don't see and coax or optical out, but just did quick search. Keep in mind that a lot of that marketing material is just that. I love my unit, but you can't believe everything you read. Also that's cheaper the IDoing or Joying. I think the key is make sure it has the key connections you want(optical, coax, HK my case) and that it fits your car.
Idoing is reseller of various types of kanged android head units.
Would be good to know factory/manufacturer or unit - sounds like it might be an FYT? You will then be able to know what rom options and mods are available from the forums.
Manufacturer can generally be identified from MCU version, what is the full MCU version listed?

IDoing is FYT, they are the only ones with the canbus for the HK system in my car, but that's fine for seryser as he/she has base stereo., but with no HK I recommend getting a unit with optical or coax.
Just a note on the WRX install, you will be tempted(as I was) to not drop the drivers air bag and try to get to the 10mm bolt on that side. DROP THE STUPID AIRBAG!!!!
It's really near impossible to get enough purchase on the bolt unless you do. I wasted an hour trying to not drop the air bag and gave up and had it done in 5 min.
When you put the new unit it, they are TIGHT, snap the clips at the bottom, bend in the clips at the top, then push REAL hard in the top of the screen to sanp the middle clips. They will snap in and what a beautiful fit this unit has. Make sure you run all your cables where you want them before you snap it in! You get 3 usb, I removed the cigarettes lighter under the unit and cut it and plugged it to have one USB in snapped in, ran the other two into the glove box along with the stock usb plug(was amazed it was long enough), then you just plug it into the adapter and one USB plug right in the glove box. Now I have one under the unit, one in the glove box, and 2 in the center console.
I just found the USB Mode toggle on the UIS7862 IDoing. It's the "..." menu at the root of developer setting. Two items in Chinese, top one is host mode, bottom is device mode. Got USB Debugging working fine even with usb-c cable from my laptop.

I can post pics later, but if you can get into developer settings. Immediately in the top right there is a menu button(...) click that and there is one option "USB Configuration", click that you get a popup with 2 options in it in chinese. The first is USB Host mode and the second is Device mode which will let you do USB Debugging from a laptop.
again this is on my IDoing, YMMV

So my unit arrived today:
https://www.aliexpress.com/item/32955093508.html
Got it to the point of plugging it in to test in the car.
Adding Heating controls vents was a Piece of Cake and this thing looks amazing
Tested:
Screen: Fast and gorgeous responsive, seems very good in bright sunlight
capacitive buttons:, work well , Reset and reprogrammed and much better. Also Illumination is working with custom colors.
Well Documented low volume buzz... Yep it's there, goes away if you mute the radio. Will look for setting to reduce perhaps as well as talk to IDoing
Harman Kardon Canbus, Works plug and play. One issue that may be related is the Fade controls don't really work to fade to rear as they mute the rear, while balance controls work fine... Talking to IDoing now and they just confirmed that any factory amp radio has this issue.
Wifi 5ghz tether, works flawlessly, get 50mbit off my cell. Not the fastest but more than good enough
Play store/google account setup: works flawlessly. Have installed several apps already
Waze/GPS: works flawlessly
USB: 3 dongles, all work for USB Drives, haven't tested for phone connection
Flac: Works off all 3 usb(one main reason I went with this unit)
4g: Working well with t-mobile, not working with verizon. Verizon shows as full bars, bars when I went more urban, but there are no APN settings and I cant get data to work.
Bluetooth audio: works ok, sound doesn't seem fantastic, but i will probably never use.
Android Auto: Wired works great, can't get wireless to work even though my phone says the head unit supports it. Wired it's very fast and responsive and looks great.
Carplay: works wired and woreless, didn't test much as I don't use apple except for app testing.
Fubo/Video: Works very well screen is gorgeous
Developer options: IDoing gave me codes
Launcher: Pretty flexible with different options.
Got USB Debugging, ADB to work today. In developer setting there is 3 "..." at the top, in there is USB mode, top is host mode, bottom is device mode(ADB).
Once I got ADB going I got SystemUITuner granted permissions to control immersive mode for Waze and the like.
Custom Launcher: Got custom launchers working with a trick to use the setting in Nova to set default launcher. Now Rocking Car Web Guru launcher. Also Like Car Launcher Free Version.
Split screen : woks well and is even remembered as last view on soft boot.
Geekbench: 500+, 1300+ very pleased.
android auto with Head unit reloaded: tested with dev server method. Works well with wireless, but UI layout is pretty bad.
Console USB Adapter: Bought from amazon, works perfectly. Now 4 functioning USB
USB access for File Manager : doesn't work yet
Music Apps: do have access to USB
Automation: Used Macrodroid to start Android auto whenever the phone usb is plugged in, or to start spotifiy if no usb and wifi connects. Will do some more of these.
Overall:
Bummed about the rear speaker control, will have to see how much it affects my listening, found subwoofer control an tweaked EQ, sound is quite nice, still wish fade worked. Ok next note to others, make sure you calibrate your EQ with your back seats up. I forgot I had put them down to get my bike in and that was half my disappointment with the sound. Yes I still wish I had fade, but this thing sounds Really nice once dialed in.
The buzz is "irritating" that it exists, but unlikely a real issue for me.. Totally inaudible when car is running.
Otherwise this thing is pretty sweet so far.

What a good review!!!
Really "irritating" the permanent buzz. Only dissapear with volume to zero every time I turn on the unit. If somebody find a fix i will be more than happy

Yes I agree, at tis point it's the only real gripe I have with the unit. The thing is amazing compared to the crap that Subaru put in.
The issue seems to be pretty common on these chinese units, which is why if I didn't have the HK setup I would have bought one with Optical or Coax. Honestly you can't hear it when listening to music, but... If I ever pull the unit out again I will try to ground the board to see what that does.
IDoing has "tried" to be helpful, and they are extremely responsive on aliexpress.
I'm glad you found my review useful.
So I managed to get APN setting for verizon to stick, and I ca see the verizon network if I use a replacement mobile network settings like from CWG, however even though it will connect and I have the APN it sitll won't get any mobile data on the verizon network. I'm beginning to think they have it hardcoded in the System to only work with t-mobile. Either that or Verizon is rejecting data requests from the device even tough it lets it connect. I've tried with both true Verizon Sim and an Xfinity Mobile Sim(Both verizon, but different APNs).

Do these buzz even if you don't have the hk?

I believe they do, only way around it without playing with internals is to get one with the coax or optical out and use that, then it's digital to your amp.

Think it might be possible to add some kind of pass-through filter/adapter to the RCA leads which could help reduce or eliminate the buzz?

Question Which UIS7862 unit should I buy?

Im looking to get a new head unit for my car (Corsa D 1.2 2009), and was planning on getting the Teyes CC3. I then found out through this forum and elsewhere that its essentially just being resold? I then found other units like the Mekede M6 Pro, etc. Im not sure which one to get, does anyone have any suggestions? Or information that can help me decide between all of the UIS7862 out there?
Im leaning towards the Teyes even if it is slightly more expensive, as ive heard good things about their support and firmware updates.
But ive seen units for £180 (6+128gb) with better spec than the teyes at £250 (3+32gb)!
I mainly want good audio (so a good DSP and AMP chip), and i want polished looking software and not having to deal with the android stock menus as much.
For someone in the UK, what are peoples suggestions?
Thanks
Gershy13
Mekede M6 Pro (Youtube, another UK guy like you). Personally I would never buy a T'eyes. Too much closed source and paid software.

Thanks,
Would you be able to tell me what the main differences between going with teyes and their closed apps (some examples of why theyre worse) compared to something that isnt locked down? Like mekede or anything else.
Another one i found is OSSURET? I was thinking of the S8

It seems to have a slightly higher clocked processor too. And for the same price as the mekede i can get maxed storage and ram. Thoughts?
Are you planning to listen to FM radio? If you are I advise you to stay away from any FYT based head unit. If not go ahead.

Curious as to why? But no never planning on using the radio. (Spotify only)
AF function (changing frequency of radio station when signal gets too weak to a stronger signal) doesn't work on FYT head-units. If you're in a country that doesn't use DAB this should be a deal breaker.
Wish I knew that before ordering mine, but I didn't even know it was an FYT head unit. xD
Also be aware that the Bluetooth pairing functionality is quite unintuitive to work if you plan to share data via bluetooth from your smartphone. It does not connect automatically so you need to connect manually every time.

Ahh okay thanks. That's fine I don't mind using WiFi for internet sharing. Or even usb if it's supported.
And yeah no plans to use the radio so we're good.

are you sure about that, have you tried https://forum.xda-developers.com/t/...nd-sc9853i-fyt-devices.4387965/#post-86251871
Also, the BLuetooth on these units, comparatively, is very good, with proper BLE support via dual Bluetooth to support things like radar detectors (Valentine One.)

Yes, I am sure. Go over the thread and Kotix explains it why he can't fix AF.
He made a work around for an user to easily switch between saved frequencies of the same radio station. But this is manual switching that an user needs to do by himself, not automated. This is not optimal when you're driving.

My Bluetooth connects immediately every time I enter the car.
I also find FM radio to be excellent using NavRadio+
AF isn't a deal breaker for me. I only have 1 station that jumps between frequencies occasionally (BBC Radio 2) and Kotix workaround is intuitive and easy to use.
The fact that it doesn't affect doesn't mean the issue isn't there.
Bluetooth works well. Bluetooth 2 doesn't. There's the simple work around of automating an wifi hot spot when your phone connects to Bluetooth.
It's true the NavRadio+ is a big improvement but the AF doesn't work at all.
My bluetooth always connects to phone 1 but if you have phone 2 it will not link to it, you have to pair it manually even if it has been conected previously. That's a shame.

Same here - second phone never connects automatically. Really annoys me because we are two daily users of the car :/
Yeah, I know your pain lol. I suppose the manufacter would need to invest on a better bluetooth chip for two phones to work. I come from a Pioneer with bluetooth from 2008 and it already allowed to pair 2 distint phones at the SAME time!!! And it still works.

A recent thread addressed this and a reseller replied with a config.txt that seemingly results in the Bluetooth trying the last phone used and failing that trying the next phone in the list.
Does Bluetooth only reconnect to the last device used?
My unit allowed me to pair multiple phones (my wife and daughter also drive) but the Bluetooth system would only reconnect to the last phone used. So if I drove the car last, and then my wife drives, it won't connect to her phone without manually...
forum.xda-developers.com
I can see a few lines that might be relevant but I've no idea what the secret sauce is to change the behaviour.
Backup your current config.txt and give a few of them a try if you're confident.
Lines I can see that "might" relate to Bluetooth pairing...
ro.build.go_lasttop=true
sys.fyt.bluetooth_show_voice=true
persist.btpair.ssp=1
persist.fyt.enablebtvoice=true
persist.btautoconnect.count=3

Hum... thats interesting stuff. Thanks. I'll do a little more digging and give it a try if I discard the chance of bricking something.
