Android Tablet in car (bmw)

In the near future once an android tablet comes out that has GPS and dosnt cost me an arm and a leg i will be intergrating it into my bmw.
Since many tablets have usb host and on the web i can purchanse an ibus to usb adapter which people use when they make a car pc would this work with an android tablet? to control volume tracks and maybe even voice control/calls etc.
Does anyone know if anyone is working on the android software which would allow the tablet to recognise the ibus signal? this would be purfect for me.

Can anyone help?

I doubt that you'll get a helping answer soon, because there are not many people knowing about the IBUS.
For people who don't know what the IBUS is: It's a communcation bus used by BMW for controlling most of the cars electronics (light, radio, navigation system, electric window, ...). There are adapters for controlling all these things with a PC, so it should be possible to do this with an Android App.
But I'm affraid that there is none available at present. Also I think the app is not the only trouble: You'll need a working driver for your adapter, too.
So long

Galaxy Tab. Since you have a Beamer I'm going to assume that you have some spare cash, the Galaxy Tab should have GPS, and I'm sure someone will make a car mount for it, or you could be the first .

If you havent gone to mp3car.com go there and check it out, ill be doing the same thing in my e36 pretty soon, although i have an external touch screen im going to try and link my g2 to

Im sure that eventaully someone will create the drive/app for this. If i can use my phone with a bluetooth obd2 connector and rear my cars information on my phone surely what im asking is do-able.
cheers for the reply

My initial plan was to do that with my htc desire but unfortunatly it dosnt have tv out or usb host (OTG).

old post, but i might be on the same wavelength as you, except with some changes.
android tablets will already do most everything you need, so my plan will be to ditch the head unit all together. in the spirit of the carPC and liliput touchscreens, my goal is to come up with a custom docking unity in the space of a double-din (which means i'll be required to use a 7 or 5in tablet). from there, the rest is relatively easy... or complicated.
the problem, so far, is i've yet to see any android tablets with a way to extract audio without using a headphone jack. so creating a docking station will be difficult in the sense of attempting to attach the audio.
so a couple things have been going through my mind;
1. you won't have to worry about power saving as much as a carPC. the tablet will be mostly safe to run off of the USB power (hooked directly to a 12v source) or maybe through a power inverter. removing the battery would eliminate concerns of dead battery, exploding battery from heat, etc., etc.
2. most built in FM tuners require the headphones to be attached to act as an attenna. can't be that hard to engineer the headphone component to work back into the car's radio antenna, it's just a matter if there's any benefit to be gained.
3. speaking of audio, once it's out of the device, it's just a matter of conditioning and amplifying the signal, which is all proven technology.
4. there's a huge probability that i'll skip an "in service" device in favor or a wifi only one, and then use tethering from my phone. still to be decided. i'd hate to add another cell line to my already high bill.
5. most, if not all, of the tablets will have some sort of hdmi out capability. attaching the device to external displays should be easy as pie. unfortunately, everyone will probably see what is on the main display, which may not be a problem. what might be a problem is accessing and using an SD card (of any size) to store movies, mp3s, etc. you're only so limited and it might be a little bit of a pita.
anyway, these were just some of my ideas. i know the interest is out there. the "dock" is going to be a little tricky. the tablet needs to be instantly accessible (easily removed), yet secure. i suppose you could fabricate something to where the audio cable is loose enough that you could attach it before docking.

are you talking about the android-driven HUs about to be released? from my understanding, they're just utilizing it as a core OS and not in the format you're used to on a phone, etc. similar to how Ford/BMW uses MS in their systems. i don't believe it'll have access to the market, which is a negative IMO.
the HUs might be sweet, in relation to what's available, but unless it's a dedicated tablet, i doubt you'll get the functionality you'd want to expect out of Android.

If you had a phone with usb host (OTG) then i would think we could just connect a MIMO Touchscreen monitor to it and use the released drivers for it and then we would all have what we want . here is some of what i have found that might help . Lets make this happen !!!!

I'll bring this thread back to say that I have. Its an ongoing project but heres what I have so far:
http://www.youtube.com/watch?v=iBdQnFnXtgQ

any updated progress I have a 2007 335i and would be interested in getting a setup like this

Right now I'm working on making sure all of the commands work. Progress is slow since Java really isn't the best language for manipulating individual bytes (although that could also be my lack of experience). Unfortunately if you have a 335i, none of this will help you. I think all of the current generation of BMW's (those with iDrive) and most european cars for that matter use the MOST bus. This is based on a fiber optic physical layer. The supported transfer rates are in the 100's of MHz so you'd need more than a microcontroller to talk to it. That being said, if anyone wants to fund me for a couple weeks and lend me their iDrive equipped BMW, I'd be happy to crank something out

Hi TunaCanyon,
good to hear, that some other people are engaged with this topic.
I built a IBUS Bluetooth gateway half a year ago, last weekend I used to make the circuit look a bit more "professional"
I already built some piece of software based on the Bluetooth SPP example ("Bluetooth Chat") of Android SDK. It features logging ibus data (including simple packet recognition) and sending data to the ibus (with automatic checksum and length calculation). I just added CD changer emulation.
As I'm not experienced with Android programming and also didn't start with Java long ago, building a clean and working app is pretty hard for me, especially when it comes to services and threads... So after the easy datasheet reading and circuit routing part now the hard part follows.
Greetings,

General joying 13.3 inch tesla style headunit

Hi everyone,
I just received this headunit from joying that's running Intel sc9853i chipset with 4gb of ram and android 8.
In order to get it I had to email joying directly at
[email protected]
I have to say this is the best unit I've ever used. And I have used a LOT of headunits including px3, Px5, PX6, ownice, and even most recently another tesla style headunit using rock chip.
The hardware is solid and clearly high quality.
The software is not bloated like all the other headunits. Google Hotword works out of the box. Same with google maps, calls and bluetooth connections. .
The steering wheel keys are detected immediately and it even gives the steering wheel code right at the top of the app which allows for multiple different options for app launches including google voice.
The unit auto sleeps and wakes from sleep immediately with no issues.
4G works right out of the box with tmobile us sim card.
The instructions come with the actual password for the factory settings screens and developer options screen which allows you to change the boot logo.
Audio is...pretty good. It's definitely better than other units I've used and the equalizer allows for changes that I can hear. I'm no audiophile but even I can tell that the audio quality is much better than headunits mentioned above.
I can honestly say I love that all of the bugs and problems with past headunits seem to be resolved for me in this unit.
If I could make any changes it would be with the hardware where the screen interfaces with the headunit. Because it's an auto-rotating headunit (which is more gimmicky than anything honestly) the screen itself is flush and not very adjustable up and down..this means I have to have the whole unit moved forward to mount in my dash as my car has an angled dashboard. Not a big deal by any means but a minor annoyance.
I hope this helps anyone looking to buy these units.
Let me know if you have questions!

Great to see Joying is releasing new units with motorized rotation.
I am a bit sad that the ratio is 16:9 instead of a more usable 16:10.
I am very sad that it's using the Unisoc / Speadtrum / Intel Airmont SC9853i (released Q2 2017) instead of the Tiger T618 or T710 from 2019.
Also, a new unit released with Android 8.1.. Really!? Android 11 beta has already been released.
I know Joying more of an assembler and not really a manufacturer and has little to no access to the source code of the software / firmware their products run. One would hope that they could "encourage" their supplier of coreboards (the pre-built board with processor / firmware) they all use to produce something more modern.
I am in the market for a new stereo for my car and purchased a Joying unit years ago. It's too slow for me now and I want to upgrade, but buying 4 year old product for top dollar is not something I am likely to do.
Did your unit come with the DSP chip for proper EQ adjustment? Many of the assemblers do not include the DSP chip to cut down on costs.
For those that aren't interested in the rotation perhaps this is a better unit for you: Joying 10.1" 1280x800 no rotation

How much did you pay for it?
And is it 1-DIN or 2-DIN size?

I am in the process of buying a 13-inch rotating headunit and it's either going to be this Joying unit or some other Chinese unit.
The Joying has the latest Intel CPU, SPDIF out but is Android 8 and 2-DIN.
The other one has the PX6, no SPDIF out, but has Android 9 and is 1-DIN, which I prefer because it will allow me to fit it an inch higher in the dashboard.
What do you notice more in real life, the Intel CPU vs. the PX6 or Android 9 vs. 8?

Yes dsp chip. But as I understand it dsp is a pretty deep field in which I don't know very much. I don't know if this answers your question but I am able to change eq settings for individual speakers at I think 11 channels..let me know if there's some way I can answer your question better than that.

100% the joying intel cpu is waaaay faster and has much fewer bugs than the PX6.

I'm currently working on video reviews of this unit. Thus far I've gotten the unboxing and install videos done, hoping to have reviews out in the next week or two; they take a surprisingly long time to shoot and edit.
Unboxing: https://youtu.be/h__Zc0fwOtw
Install: https://youtu.be/Xq1FvLoKESo (This unit turns out to be too big for my car's dashboard and no head units really fit well in the car because of the deep recessed design.)

Just confirmed with Joying, they have now implemented the 13.3inch head unit with Android 10. Can purchase it through joyingauto.eu/china-post-shipping-fee.html

Thank me guys, I ordered one this morning and talked the price down from $500.
The new unit has the UIS7862 CPU by the way.
Now I need to find a suitable Canbus cable for my 2015 Mitsubishi Outlander. Any suggestions are welcome. I am in the Netherlands by the way.

How much did you pay? was it the 13.3inch display with android 10?

I am getting the 13.3-inch Android 10 version and I paid EUR 425.00 including shipping to the Netherlands.

I finally installed the headunit today in my 2015 Mitsubishi Outlander PHEV with the OEM Rockford Fosgate amplifier.
I used this cable: https://connects2.com/Product/ProductItem/CTKMT11
But I can't get any sound.
I think it might have something to do with the Canbus type setting in the hidden settings menu, but I have no idea which one to select.
Also should I set the option for External Amplifier on or off?

I've read elsewhere they chose Singapore in the canbus settings and it worked

That's a pretty massive screen. Are you able to turn the brightness down enough at night so that you aren't blinded?

External on - I would think (if you have the Rockford amp)
Did your original have GPS ,?
The black box part of your cable has to be correct, you most likely have the wrong one and the amp is not being turned on.
The Mitsubishi units are a pain from what I've read
Possibly aerpro Mito-02 cable or CHMB4C patch cable
Check which is suitable for the outlander
Contact joying ? You might need the canbus cable. Definitely on older cars

I gave up tryi9ng to get the adapter cable working with the OEM Rockford Fosgate amplifier. The manufacturer wanted me to send it back for reprogramming without any assurance that it would work after that.
I have now fitted an Awave DSP-6 DSP amplifier that gets the signal from the headunit through optical out. I have fitted a 3-way set in the front doors and on the dash.
So yesterday was actually the first day I could use the Joying headunit.
It is still buggy with various apps repeatedly closing and several time the stock launcher refuses to show the app drawer. I have installed Nova Launcher.
One thing I can't figure out is the split screen function. With such a large display this would be very convenient. What am I doing wrong?

You don't tell us what you already tried. Always do that first! I am now risking to spend my precious time on something you already tried.
Also: All the default Joying (FYT) apps like music, radio, video, settings, etc. do NOT function in split screen as those stupid apps don't support it. Their screen layout is still based on android 1.6 and has never been changed. Therefore they can't use the multi-window feature of Android 7+.
Anyway: If you have two apps started, like your nav app and your (non-FYT/Joying) media player, you go to the rectangle in the top-right of your notification bar. If you tap it, you see the active and last used apps.
Tap & hold your desired app. On both left and right side of the screen you will see two grey areas (after 1-2 seconds). Draw the app to either the left or right area. Then select the other app for your splitscreen display.
Alternatively: If you use the touch-assistant (the little white dot normally in the top-left), you can tap it. One of the options is to start split-screen as well.
This has also been described in #19 of my SC9853i Q&A thread.

Obviously as a long time XDA member I tried this already...
I just got word from Joying that the split screen function is not supported on this Joying model.

Indeed . You have a screen the size of a cinema screen and you can't use split screen. Unbelievable.
And they really show a split-screen on their website !!!

Question Mekede /Navifly 7862 CAN code.

Hi.
Can any of you add modified CAN codes to the 7862 radio? I have a Peugeot 308 SW car. Unfortunately, it is not on the car list. I am currently using the setting for the Peugeot 408. But not all functions are working. The steering wheel rotation codes that are used for the moving guide lines for the rear view camera are missing.

depends who is the manufacturer of the decoder, however try XP, or OD or check all, Android Settings > Car settings > Factory settings (password: 126) > Canbus tab > Select the manufacturer of your canbus decoder and the car model, or select the closest match if you cannot find exact model, e.g. volvo xc90 not on list but xc60 available. I hope it make sense.

I'm working on an open source CAN bus box for these sort of situations. The idea is that it fits exactly into the connector for the existing standard CAN bus boxes all these units use (so it will work for PX5/PX6/intel/UIS7862 etc). I've had a similar problem with my Audi A3, where the button functions are incorrect and unchangeable. My car also has an OLED display on the gauge cluster which doesn't show anything useful without the stock head unit (my primary motivation for this project). I'll make a more detailed post about it here once it's working smoothly in my car. For now I'm still working out a few hardware and software kinks, especially since I also need it to control my external DAC and gauge display.
To configure it for your car you will need to know the CAN bus communication rate, as well as the packet ID and bits changed for the following functions:
ACC on
Park
Reverse
Headlight/interior illumination brightness
Optional:
Steering wheel buttons (if you want SWC)
Dashboard display (if you have one - mine operates as 1 line 20 characters in my preferred configuration)
Interesting parameters to monitor (fuel consumption, temperature, instantaneous speed, etc)
I'd also suggest being familiar with modifying Arduino code to change the packet values as I won't modify it for anything other than my Audi A3 8P. The way this data is coded can vary quite a lot car to car - for example in mine the brightness is coded as an integer from 0-100. You'll also need a way to solder the parts.
JLCPCB is insanely cheap for ordering boards if you're a new customer, and the rest of the components cost ~$30. I may build and sell some of my extra boards if there's interest, but I won't be providing any software besides for my Audi A3 8P. I'll update within the month, as I don't anticipate needing to change anything this point besides software, but only have 1 day a week to dedicate time to this project so progress has been slow.

Salut.
Poate cineva dintre voi adăuga coduri CAN modificate la radio 7862? Am o mașină Peugeot 308 SW. Din păcate, nu este pe lista de mașini. În prezent folosesc setarea pentru Peugeot 408. Dar nu toate funcțiile funcționează. Codurile de rotație ale volanului utilizate pentru liniile de ghidare mobile ale camerei de vizualizare din spate lipsesc.

Hi @COASTER19 .
Thanks for posting about this, always good to hear about real development work.
I for one would be very interested to read more about your project, would you consider posting more information.
Also, there is another thread discussing similar work you may not be aware of, so have posted here.
CANBOX , CAN decoder reverse engineering
Hi All, I have a PX5 radio that was supplied with fittings for 2006 Toyota RAV4 , sadly it didnt come with a CANBOX and supplier was not able to provide one that matched, I managed to get my hands on a Canbox for VW unit and decided to reverse...

hi all, i am new here and thinking to buy navifly HU
I have one question, dose the unit support climate control for AC? can I control my AC from unit?
The other question, can i add 360 cameras system?

It depends on whether your car exposes CAN-bus to the head unit and whether the provided CAN-bus box supports it. Generally, the answer is no unless specifically mentioned in the listing text. Navifly support doesn't speak good English, so I wouldn't expect a correct answer from them.
@marchnz I posted an early demo of the project on Youtube and have attached the latest schematic to this post.
I'll start a thread in a few more weeks once I get the optical audio working, but the current board layout probably needs another revision before then. I had to use a rotary tool to cut part of the board so the connector could physically fit. CANBOX looks interesting, but also works very differently from what I'm doing. I'll look into it more once I have a fully functional stereo again, as I'm definitely interested in trying to get some of those functions running.

Fantasic work, really like the approach to steering wheel keys.
What is selected for CANBus type on the unit to enable the split between analog steering wheel, Illumination, ACC and vehicle specific CANBus signaling say from car doors, AC etc?
I am very interested in making one and having a go at modifying the software for Toyota specific vehicles, if you're comfortable with releasing and commenting the source? Understand if you're not though
Great video. Thanks again for contributing to real development. Your work deserves its own thread!

Illumination, ACC state, Park state, and Reverse are just +12v signals onto wires. Normally, everything else happens over the serial communication, but in my case I use KEY1/KEY2 with selectable resistors for SWC.
Vehicle specific stuff such as reverse radar sensors, climate control, and door status would require reverse engineering the head unit's 2 wire serial protocol. Luckily it does appear at first glance that the protocol is the primary focus of the CANBOX project.
If there's a way to select an app to open over that serial connection it would be really convenient, but I don't think that's an option discovered yet. It would allow the mode carousel to be controlled entirely from the microcontroller which would be great. I loved how HAL9k's ROM on my PX6 allowed me to customize this, but my PX6 ran incredibly slow for some reason (20+ seconds to open maps). The 7862 is far nicer hardware despite the unpolished software, so the preferable option to me. Optical audio output is also great compared to the noise in both the PX6 and 7862 amps.

Ok. Couldn't find problem like mine. After starting car my dashboard HUD is in Chinese. Can't find anything like original radio settings to change it. Any ideas?

Will use opcom to do that as navifly 7867 doesn't have setting for that inbuilt. Lots of cd400 radio settings are gone. Thanks.

I dont know what that has to do with using translate on your phone to find the language menu on your head unit, but if that spins your wheels.

That means I can't change settings from head unit as that setting doesn't exist. It's not head unit language I'm talking about, it's dashboard display.

So using Google translate is impossible, hence I mentioned that opcom is needed.

With the Google translate app on a phone, you can use your camera to point to the text and translate it.
Perhaps you can use that to navigate to your dashboard settings to change the language?
Don't know if such a setting exists, though...try it and let us know.
Edit:
So, if with your previous head unit, that's where the language settings were found and not directly through another method, then the head unit that replaced the factory head unit should provide those functions.
For the TEyes CC2 and CC3, once the proper Canbus setting is specified, I believe there is a Car Info app or something similar, that provides access to vehicle specific functions/settings. For the CC2, which I have, there are additional menus that are available in the normal settings when you specify a Canbus adapter. Have a look around your settings to see if you can find anything like this.
Question...did this just start happening or is this the first time with the head unit and the Chinese text in the dashboard is showing up?
Question...have the head unit language settings been set to the proper language?

Issue is. Supplier sells unit with CANBUS for generic GM as Chevrolet to European cars such as Opel Astra. Settings for canbus is GM/Cruze/cruze_manual, and kinda covers most of ECUs. In settings under 3368, settings for language don't exist. It covers basic personalisations, lights and doors, not nothing like that. At the moment decoder is by HiWorld. I got GM compatible one from Rise but don't know how to force unit to recognise it. When I connected it in canbus settings i couldn't na choose Rise. So I got an OBD OPcom/vauxcom and will change language trough that. But thanks for the tip with translate. I know that display by memory, it's just annoying to see avarage consumption as bunch of lines putted together.

Dostałem kompatybilny z GM od Rise, ale nie wiem, jak zmusić jednostkę do rozpoznania go. Kiedy podłączyłem go w ustawieniach canbus, nie mogłem wybrać Rise. Więc mam OBD OPcom/vauxcom i przez to zmienię język. Ale dzięki za wskazówkę z tłumaczeniem.

Well.... It's not that easy on my unit. Or maybe decoder is wrong. Basically no language setting. And most of settings are empty screens. Canbus is set as a Chevrolet Cruze. I have a second "Opel" canbus unit but not sure how to connect it. Does it require reset if the HUD or is it plug and play?

Question Alternative FM radio app for FYT-based Android head unit

Hello all,
I have an Atoto S8 which is a FYT based Android head unit.
MCU Version:
2021.04.26 13:48:17 YUF_53_L6315_G32P64F64_Ver: 1.0
CPU: UIS7862 Octa-core
I was wondering if anyone knows of or has an .apk of an FM radio app compatible with the FYT head units? I tried every app around and none of them work. The Navradio developer is still porting his app to this platform, so I was wondering if there's something else I might try meanwhile.

There are re-skins, but AFAIK the radio bits are part of the proprietary MCU

But if I got an .apk from a Joying head unit, it might work no?

I'm not so sure about that.
I think you would have to do some hand editing of some files at the very least. (To put in your fyt build number)
There is more info on it at the other forum.
I looked into it for a second weeks ago, but then I bought Poweramp and haven't really used anything else.
I agree that the fm radio all looks like crap though on my Mekede

Poweramp works with online radio?

Apparently it does. That's not what I meant, though.
I procured some 15-30 gigabytes of songs from different playlists from another source.
(I have to be vague because of forum rules)
Anything else I want, such as podcasts, I just stream via Bluetooth.

If your Atoto S8 is indeed a FYT unit, it might work.
What you carefully need to look at is the name of the apk. It has to be exactly the same as the one on your Atoto unit including installed libraries.
And then you need to write the corresponding lsecupdate.sh file and use the corresponding lsec6316update binary
and off course: make a backup of your current one.

I'm working on porting NavRadio+ to FYT units.
This last weekend, after 2 months of tries, i was finally able to get sound out of my app.
I already have control of the radio commands and infos so it's just a matter of put things together in the right way and iron out all bugs. Then i could release a first FYT version probably in the first days/weeks of the new year

I did not know you were working on this.
Please take a look at this github from lbdroid. It contains a lot of useful "reverse engineerng" information for the MCUradio for the FYT. It is still from the Sofia3GR but as far as I know hardly anything changed.

The original fyt radio app now contain code for all the platforms and each platform use different approaches. The hard part was to understand which part of code is used by each platform and how.
Sofia units control radio and audio through MCU.
UIS7862 use the native jni libs to control the radio and audio is started by MCU.
Right now I'm working only on more recent UIS7862 units, i don't think I'll adapt it to Sofia or other older units.
I know that units with canbus use another APK too (com.syu.carradio) but it's not totally clear to me what it does exactly. Can somebody explain me it?
To make my app to work, because of the native libs, is mandatory to install in OEM folder a copy of NavRadio apk (not necessarily the full apk, even a fake app with same package name is enough to set NavRadio as system app).
To do this i have 2 ways:
- directly from NavRadio for rooted units with some root commands
- downloading a zip update package to flash manually the APK in OEM folder
If you guys have other/better ways to do this, please tell me, I'm new to these kind of units..

I did "some" checking on this app a couple of years ago as I had a Skoda with Canbus. The standard radio in the Skodas (and I assume in all VAG concern cars) are partly controlled by the CANbus. The Skodas use an extension on the standard CANbus commands to switch on/off the radio in the cars when ACC is switched on/off. This is NOT a direct wired coupling of power, but really a digital on/off signal from the CANbus.
My Skoda had a simple Swing radio (hence another Android unit), but other Skodas had the MIB1 Amundsen/Columbus unit (navi/media/phone/radio/tmc and car menu). The car menu inside the radio is also controlled by the CANbus. My guess at that time (not having a MIB1 amundsen/columbus unit) was that that was also "streamed" through the carradio app.
Note: I am only sure for the on/off, the rest is an educated guess. And I assume other cars with CANbus displaying/changing "stuff" via the radio, instead of dedicated hardware buttons, do the same.
Maybe other users having a VAG (Audi/VW/Skoda/Seat) car with previously an MIB1 (or MIB2, but why replace that one?) unit and now an Android unit might have more info.
Please share.

And another question: RDS-AF on all FYT units is incorrectly implemented and already since early 2016.
Does your app has a properly working RDS-AF?
If I drive in the Netherlands from North to South (or the other way round ), I sometimes go through 7 (!) frequency regions depending on the station, but at least through 4.
Working RDS-AF functionality would really be THE reason to switch to it.
Edit: I know it works for Topway and the like, but I want to know whether it also works for FYT.

Normally AF is handled directly by radio chip. I still haven't investigated how it work on fyts.
My app can only enable/disable AF and on some units you can set the sensitivity of reception.
On MTC units that also receive the radio station ID (PI code) i added a function to merge the alternative frequencies in the same station preset in an array so that you can easily switch between them sliding up/down on the screen.
I can see in the logs that also fyt units receive the pi code but only at native libraries level (c++), i cannot handle it in java.
I know that we can change sensitivity and read the signal strength so probably something is possible to improve AF.
We'll see...

A lot of Philips TEF6686 radio chips are used and RDS is part of the chip. Some of the cheaper units use a TEF6851 which does not have RDS. Or the budget STMicroelectronics TDA7786x which does not have RDS either.
But it is still the software that "should know" how to retrieve and use the RDS info and in this case specifically the RDS-AF. The FYT software is not doing that correct.
That's why I switched in my other "deceased" car to a DAB+ module using @realzoulou's DAB-Z which uses proper "service following" (as RDS-AF is called in the DAB+ world).
That was a great solution, but I still prefer not to have extra hardware connected when it is not necessary.

I looked a bit at the logs during RDS-AF and it definitely is working wrong:
AF should search for an alternative frequency of the same station (identified by the pi-code), but somehow,after a while, if the signal strength is ok it switch to a station with a different pi-code.
All this seem to be controlled by the native library fmjni.so but i have no idea how to modify a c++ lib (maybe a revers engineering?)
Maybe I'll find some other way to handle AF using the logs but i can't promise anything right now.

I now think it even works differently for the standard FYT radio. My experience so far is only on Sofia 3GR (2 models), a PX5 and a sc9853i, no experience with the uis7862. Hopefully the uis7862 will arrive this week.
The RDS-AF only works for memorized stations. If I want to follow one station, for example NPO 2 FM, through the Netherlands, I need to add 4 frequencies (or more) and memorize these as presets.
It seems the radio app/mcu does not interpret the RDS-AF signal itself, but it seems to check (part of) the RDS data it has for a certain station, with RDS-data from other memorized stations. If part of it is equal (which part? only the station name itself?) with that other station (which you have to have memorized, otherwise it can't compare) and that station is stronger, it will switch to that station. If it can't find a stations from its memorized stations it seems to just select the strongest "whatever" station. This means that I have to blindly save 4 "NPO 2 FM" stations in the presets. And this for some other preferred stations as well. And of course: 1 frequency is what you can easily hear and set, but the other frequencies you have to google or so, because at the moment of adding it to a preset, you don't not have (sufficient) reception for that station.
"Real" RDS-AF should check the alternate frequencies inside the signal. Not do a "does some of the data look like a station I already have in memory".
I am a "restless" listener and listen to multiple stations. I switch when there is talking I don't like, a song I don't like, etcetera. I can't even memorize my five preferred stations in 18 presets.
In the Netherlands we have another deal breaker: FM frequencies are sold every five years and anyone can pay to it. It really means multiple different frequencies, whereas in some countries you only have one frequency for a station through the entire country, like in some countries in Azia.

I believe that standard radio receivers have a double tuner to handle the AF: one that keep the station tuned and one that scan all the frequencies to find the better one with same pi-code.
On MTC devices even if it's not perfect, it work correctly, the station is kept while the second tuner scan silently all frequencies until a new one is found.
On the FYT device i can hear changing frequency continuously until a stronger one is set.
I don't know yet if it try to tune the preset ones or try to find some other but anyway it's definitively not working correctly.
I'll dedicate more time to it after the first release of NavRadio app.
Right now on my app work like original app (so it doesn't work).

Question New head unit unsure of model number. Vendor is is Navifly/mekede

Looking for some info as I got a new head unit from a friend and was looking at how to identify the specific model number and features and update firmware.
HWget info has manufacter as 116 boardtype F, platform 6315
it has a sticker that says 9inch/836/4g/6+128/720/B1/CP
I know it is a 9inch 4g capable, 6gb/128rom, 720 screen with built in carplay
I don't know what the 836 and B1 mean.
Some additional questions beyond simply identifying this:
EQ says "surround sound has been closed" when you select the surround tab
Can you get carwebguru to recognize the BT player?
How to tell if this can support 360?"
can 360 be added (am conformable with soldering on the mainboard)
carlink 2.0 does not connect to phone
what is "plug in serial device setting? Has options "accelerator / accelerator3b / kq TPMS / serial plugin 360"
I thank you in advance.

Ok well that's what pops up when I copied and pasted the information you gave into Google. You can't say something isn't real when I show you proof contrary. Also if you can give more info like an MCU number instead of the vague HWinfo results people can actually help you pinpoint a specific model instead of "supposedly fake" head units.

Manufacturer ID =116 already limits it to Mekede/NaviFly, Prelincar, Hencheng, Yiling, Hopod, prelincar, coho (and a few more) where some of them use the "YIN" identifier in the firmware. So you could use a Mekede firmware which is still regularly updated (latest update firmware 23 September 2022)

What do you mean with the MCU number? The MCU in all the 7862/8514a FYTs is identical. The MCU firmware inside that identical MCU might be slightly different dependent on the hardware, and that is determined exactly by the manufacturer id (displayed by the "vague HWInfo" , which lists much more info inside the zip, when that zip would have been shared).
Anyway, OP can flash a Mekede firmware with manufacture id 116, or a Joying with id 43 where he needs to update the AllAppUpdate.bin to put in the right manufacturer id (and/or bluetooth id). You can get that info all from the HWInfo.zip files.
The model number is completely irrelevant for a firmware flash. 9" 10" only differ in having 360 camera software or not.
Only difference make the Tesla style units as they use a different screen rotation and slightly differently built android apks.

I updated using medeke firmware to latest and eq surround sound is fixed, as is carlink.
Still no idea if carweb guru can be used for BT audio control (as I do like the look of some of the themes)
360 cannot be added internally since the IC is not sold independant the unit. maybe I'll find a donor unit someday.
Still no 100% sure on the "plug in serial device setting" but I'd imagine that is used for teyes front radar, or some other accessories. I have seen some 360 boxes that have an RX line to an android head unit so maybe that is what "serial plugin 360" is? which would let me add 360 without the IC, since the box would have it.
Appreciate the feedback.
