DAB+ GA9251b stuttering - MTCD Android Head Units Q&A

Hello,
I own the EONON GA9251b with the corresponding DAB + USB Dongle from EONON. Unfortunately, the transmission stutters so extreme that you can not hear the music. The connection always has at least 3 out of 5 bars. The APP of "realzoulou" I've already tried and an alternative DAB + antenna synonymous. Both did not improve the result. Maybe one of you has an idea.
I'm happy about every tip.

Enonon G2110 with android 4.2 double DIN car stereo

I have an Enonon G2110 with android 4.2. It has RK3066 1.6Ghz cortex A9 Dual core, DDR3 1GB. I am overall happy with the unit but I do have a couple questions for you all with this stereo.
1, The SWC controls randomly stop working and will stay not working until I reboot the unit. It is hooked up using the SWC1 wire through the SWC board on my steering wheel and hooked back to ground. It is the resistance type where every button has a different resistance. It programs correctly in the SWC program on the unit. I also have the canbus set to none in the "factory settings" area.
Any fix for this?
2, Bluetooth. When connected to my phone (LG G3) and making or receiving a phone call, the volume is super low through the unit. I have the unit hooked up using RCAs only through an amp in my car. The bluetooth connection for music works fine and is the correct volume. Is there anyway to turn up this volume on the unit? Or another program for bluetooth connection?
Also I can't get my PLX devices bluetooth KIWI to connect to this unit. I have the program TORQUE to obd2 monitoring. Not sure if its just an issue with the bluetooth program or something I am missing. The KIWI connects and works fine on my G3.
3, Screen flicker. My car has auto headlights. I have the headlight input wire hooked to the unit to change the brightness depending on day/night. When it switches modes from day to night the screen flickers for about 3 seconds. Is this normal? Any fix for this?
4, Google services stopped error. If i happen to kill the car and have to restart the engine, the unit says shutting down and the screen turns off for a moment and then back on. When it comes back on the error "google services has stopped" and I hit OK. Is there away around this? (besides not killing the car of course) It's not a big issue or anything but its something I have noticed.
I tired asking these questions on someones post but it got lost in the shuffle. Any help with this would be greatly appreciated!

Major problem, Bluetooth music connection to car

Hi, has anyone run into this?
I'm used to play music from my phone to my car (Toyota Auris hybrid) over Bluetooth. Worked good with my LG G4 but with the Mate 9 it miserable fails. BT connects but it won't play anything.
There's loads of forum messages around since nougat came out, it seems to be an android 7.0 problem that seems to be solved in 7.11
Do you guys have successfully streamed in your cars over BT? Please let us know!

I'll test it when mine arrives as I use bluetooth also.
Some other info, it really seems to be widespread and only with cars. Will check if calling actually works, I was so busy with music I forgot to check.
Btw, I have a Pebble time steel and that now has a better and more stable BT connection across a longer distance than with the lg g4.
Update next day:
Car/phone BT connection is fine.
Audio suddenly worked after a few tries but no tags visible. Much in line with what others say. Really erratic behavior.
Same for my BT speaker, perfect connection.
Another update: It played audio only once. After some more digging on other forums it seems that Android 7 is the issue. A lot of cars won't play audio over BT anymore or just handle the stream only now and than. The connection is there, the song is playing on the phone, it streams to the car but there's no sound. Oddly when you receive a phone call there's no prob whatsoever.

My Nexus 6P on RRemix rom rooted with Marshmallow does this with 2017 Audi A4. Only thing that makes it come back is to hit the bluetooth icon in notification tray off and back on, and it syncs back up with sound. Try that? It might be a Huawei bug?
I had a similar issue on my mate 8. Spotify worked but deezer didn't in relation to showing what's playing etc.. it's likely to be nougat 7 as I've got a pixel xl and no issues with 7.1 at all over Bluetooth to my car. Looking at a mate 9 though as I miss the bigger screen

I have had issues with my S7 Edge where everything connects up and all seems normal but when it plays it either delays before sound works right out of car speakers or you have to do a dance of connecting and reconnecting before sounds works properly. Also think I recall similar glitching with my previous car and my previous android phone but maybe it was previous phone (Nexus 6P) and current car (2015 Nissan Murano Platinum). Only regularly ever play podcasts in car from Beyond Pod app, BTW. Occasionally play something off YouTube but don't recall it glitching.

I have a Japanese 2014 Mazda Demio, and my Chinese Mate 9 (MHA-AL00C00B109SP01) connected, played music no problem, over bluetooth. The artist/song name shows up. But it doesn't support browsing the song library like the iPhone or Galaxy S7 did.
I also have issues to connect my mate 9 to my car (Renault Laguna 3 from 2011). I simply do not succeed to connect the phone to the car: when I try to connect, my car gives me a 4 digits pin number to enter into my phone to establish the connection, I try to connect to my car from the mobile, the box to enter the 4 digits opens and closes before I have the time to enter the digits with a connection error message.
I suspect a software bug on the bt connection with pin validation on the mate side. I can connect without issue to a standard Bluetooth speaker.
I think some cars, maybe many, just have suck computer systems. It is why I always laugh at the idea of self driving cars - like these same morons that make these terrible in car computer systems will be worth trusting to drive you around.

I also have issue on Bluetooth with my Renault Megane 2009
I had to choose nomade device to pair my mate and I have some problem on mp3 play-back that suddenly stop where has it continue on music player.
It seems to be better since I install A2DP switcher from playstore but don't know why
So I have had this issue since I got the phone yesterday and just got it working in my 2012 Toyota Tundra.
Settings > Apps > hit the 3 dots > Show system processes > Bluetooth Share > Force stop, clear data. After that try pairing your device, mine has stayed connect with frequent breaks for 5 hours today
No issues with 2 of my vehicles.
I'm having no issues at all. I'm connecting to a Tune2Air bluetooth adapter ('11 A4 doesn't support Bluetooth streaming).
same issue with Pioneer Android Auto unit.
Sometimes it works out of the box, sometimes music plays (as per screen indicators) but no music, sometimes music plays for split second and stops.
disabling/enabling BT helps
no issues when phone is connected over usb with android auto
Same thing with me as well. I have reached out to Huawei but no response. I have a US version
Just got a new Huawei Mate 9 from Optus Australia. It would not connect to my car bluetooth although it would connect to two bluetooth speakers I have. Optus technical support finally resolved the issue by changing the car bluetooth PIN from 1111 to 0000. Looks like a Huawei bug in that it can only connect to devices without a PIN or with a PIN of 0000. Checked my speakers and one has no PIN and the other has 0000 as the PIN. Hopefully Huawei will fix this.
I have a recent Japanese Mazda, as well as a gear s3 or a Huawei watch connected at the same time, and no issues with Bluetooth at all with any recent Huawei firmwares.
My Fabia plays over BT just fine, Android Auto plays it fine too.

I previously reported no issues, but now BT is very problematic. For me, it seems, the issue stems from multiple connections. Before I needed two bluetooth connections in my car: one to the car itself for phone calls, and one to a BT adapter to stream music to the car's audio system. A couple months ago, I added a Huawei watch to the mix, and things went south. Typically I'll put my watch on in the morning and it will connect to the phone no problem. But when I get in my car, it doesn't want to connect: the car itself is not connected at all, the phone reports that it's connected to the BT streaming adapter, but no music plays through it. If I turn off BT on the phone and turn it back on, typically that will fix the streaming, but not the phone call connection. The phone will report that both the streaming adapter and the watch are connected, but not the car. If I click on the car connection, it will then connect. The watch connection in the list with then lose the "connected" status, but strangely, it stays connected.
So, I can't get three devices to say "connected" in the BT device list simultaneously, BUT if I turn BT off then back on when all three devices are available, THEN manually connect the car connection, all three will work, even though only two of them will say "connected".

Bluetooth help, need some technical assistance.

I've got a new Honor 8 with the latest updates and one glaring issue. The bluetooth audio skips with my Kenwood KDC-X701 head unit, sometimes a whole song plays, sometimes I get a lot of random skips and pauses in the music like it's dropping connection. The phone is within 2 feet of the head unit so distance isn't an issue. I tried it key on engine off with everything else in the car turned off to rule out interference from anything else in the car like headlights, tail lights, alternator noise, etc. I connected it via the 3.5mm jack and had smooth playback without skipping so it's not an audio source issue. And just to rule out a BT issue with the phone, I connected to and had smooth audio with a generic Chinese BT puck in my home. This same head unit has had no issues streaming BT audio from an iPod Touch 5th gen so it's not simply a head unit with bad bluetooth, it's some kind of issue between the Honor 8 and the head unit. What I want to know is how to determine what BT protocol is in use between the Honor 8 and the head unit and then determine what BT protocol the iPod Touch used and see if there's some way to manually set how the Honor 8 connects via BT to the head unit.
Or is there something more simple I'm missing here? Some kind of power saving I need to turn off, some menu option I'm missing, I hope so.
I'm going to make sure the head unit is on the latest firmware, I believe it is but I'll check and report back if there was an update and if it did anything for the issue.
Ok so during a 5 minute call through the head unit tonight there were not any BT issues, so this must be a music specific BT protocol issue, I'm slowly getting closer to the root of it.
Seems putting it in the dash pocket directly below the head unit works better which is unnecessarily close (less than 4 inches away) and many times closer than the iPod Touch ever needed to be. So there's still some kind of issue but seems like I might have a work around, it only skipped twice in a 30 minute drive which is the best it's been.
8 hour drive today with only 5-7 drops an hour. Seems worse when I'm around a lot of traffic, sometimes or that could just be coincidence.
Sometimes it's also partly dropping, music keeps playing but other Bluetooth features aren't working like Google voice commands or making/taking calls. Weird!

Xtrons PX5 Android 10 no more audio

Hey guys. I have installed an Xtrons PBX70M164 which is an MTCE GS PX5 4G/64G Android 10 device, about two weeks ago. Things were working fine. But I noticed some days ago that I didn't have any more audio. I was not completely ready with installation because I still needed to install the DAB+ radio. So I was messing with the FM and DAB antenna's.
I do have the MOST fiber optic system in my car. I connected an MP3 player to the unit to verify if this could be the problem, but it's working as expected. Then when I connect the Xtrons radio, no more audio...
Also one other thing is that I cannot scan for FM channels on my radio anymore?
I tried to disconnect the device, factory reset and check all the cables. I'm not sure what else I can do. Is the device broken? What else can I check? Thanks!
Send it back or see an experienced auto electrician/installer.
Update: the device was actually faulty and Xtrons replaced it for a new one.

Question NaviFly 7862 steering wheel controls not working

Hi
I have purchased an Android HeadUnit for my Renault Megane 2 (2007) from AliExpress. Every function works except the steering wheel controls. The unit has the UIS7862 CPU @1.8Ghz, 6gb Ram and 128gb storage. I have installed the CanBox correctly and tried many CanBox settings in factory menu, but I cannot get the control app to enter learning mode. Does anyone have any idea? Maybe the built in key map application is at fault (com.syu.steer).
Did you find a solution to your problem yet?
I'm stuck at the exact same scenario, same unit. The support over at AliExpress mention to me to select "XP" for canbox settings. However, my canbus module is by Raise, hence I should be using the "RZC"
Also, my reverse cam doesnt work too.
Pls share your findings. Thank you!
I got the steering wheel keys to work with a custom controller made by an engineer in my country specifically for my car and my HeadUnit. The controller is connected directly to the wheel controls and the "key" wire on my HeadUnit. I had to disassembly the steering wheel base and route the cable around the original one. Now I can map every key to an action in the Key Learning app. For the backup camera, because I used a wireless kit, I couldn't use the "back" camera wire to trigger the HeadUnit to switch to it. The kit came with a receiver which only had power wires and a yellow RCA cable. I wired the receiver's power cables to the ACC power so that the receiver only powers on when the engine is running and I managed to map a button on the steering wheel to switch to the RCA input. Now when I want to use back up camera, I just need to press a button to see the image. The camera's transmitter is wired to the license plate bulb and I managed to fit it in the rear bumper.
This wasn't a "plug and play" experience that the Chinese seller promised, but overall I can say I am pretty happy with the end result. The audio quality is wayyy better than the stock HeadUnit. I didn't know that my stock speakers could get that loud and have so much bass. The DSP chip does it's job wonderfully. Also the radio reception is better than with the stock unit. The Android HeadUnit is fast and snappy. Apps open almost instantly and those 6gb of ram really help. I could compare the overall user experience with my OnePlus 7 phone. The unit also cold boots very quickly. The wifi reception is pretty poor. The unit shows 75% signal when my phone is in the car. It doesn't bother me because I put a Sim card in the unit and the mobile reception is as good as on my phone.

Thank you for explaining your solution. Seems like quite a bit of work.
I managed to get my steering controls working finally. Got the correct canbus setting and corrected a connection.
Now, I'm stull stuck with the reverse cam issue. The +12V does energize when I am in reverse gear - I tested this when I connected my cam to DV-in and cam turns on only when in reverse.
But I just don't understand why the Android won't switch to Cam in during reverse gear.
Will continue to seek help from the manufacturer. Otherwise, it's a great HU as you said. Awesome speed!

You connected the reverse wire?
Maybe this triggers the camera view of it doesn't work via the canbus.
Well, it does work via canbus, just doesnt switch to cam input automatically. Perhaps its some software settings.

Not all canbus provide the reverse signal. So maybe you have to provide the reverse signal on the separate input.

I feel that the HU knows when I am referring (CANBUS might be working here), because the 12V turns on when Im in reverse. The only issue is the HU doesnt switch to the cam automatically. Looks to me like a SW issue. Still awaiting reply from manufacturer.
Also, I realised my backward/forward buttons are swapped. Why is it I can't re-learn them?
It may not be the same for the Navifly, but on my unit, G5 must get the proper voltage to "detect" the car has been put in reverse. I'm re-using my factory rear view camera and it's a 6.5V camera. However, I had to up the voltage to 8.6V so that G5 go that voltage...then the rear image showed up. I reused the car wiring and that's why I had to do this.
Check the voltage that G5 is getting. With a canbus module, I believe there is a wire from the canbus going to G5. If no voltage, make sure the pins are in properly.
FYI, if you are using a canbus and the steering wheel controls go through the canbus, then I believe that you cannot remap the keys.
The 12 V from the reverse wire are coming from your car (or in some cases from the canbox if the information gets transmitted from car to the box via canbus).
My suggestion is:
There is a separate reverse connection (usually a brown wire) on the head unit which triggers the radio to open the app which shows the image of the reverse cam.
You could even connect ACC or B+ to the reverse connection for testing purposes.

Hi, Recently received above unit for my 2006 RS4. everything is great (much better then the M400 I had before) apart from the radio. It seemed to work for the first 2 days, then worked intermittently and now not at all. I have tried...
forum.xda-developers.com
My "cam12V" wire is from the HU and it turns on when I am in reverse. Does this mean that this signal might be coming from my canbus? If so, is there another input back to the HU to trigger the screen to display the video feed? Only other wires I see are AMP related
Give 12V to pin 2 and check if the app to display the image of the cam will start:

Yes! It took me a while to figure this out.. mainly because I'll have to cut the wire (wasn't very confident in that)
and also.. the wires at Pin2 didn't make sense! They were more like Battery12V. I did cut and tested that.
So.. it turns out its a pink wire at pin3!
I realized this as I looked at my old Dasaita wires from the canbus connector. Since canbus is a standard, they should be comparable. That reverse wire went into Pin3.
I'm really surprised that Mekede and Navifly has this pin layout printed in all their listings.. but it's just wrong.
Thanks alot for the help!
That means it works now? I think you had to cut the ACC wire according to the manual because the "ignition on" information is provided by the can box.

Yes it works now. Check out the images. The Pin2 (red) is probably ACC or batt 12V as there was no power when cut. I then cut the wire opposite it (pin10) in case I was looking at the connector wrongly. That turned out to be the headlight sensor.
After tracing the wire and comparing to my old Daisata, it turns out Pin3 (pink) is the reverse IN.
Excellent. Thanks for the clarification.
That means it makes sense to get the wiring diagram from the old radio of the car and compare it with the description of the new head unit.
In my case I had to completely rewire the harness (just if someone is interested):
Junsun V1 MTK8259 - the adapter battle (Kia Ceed Jd) / OEM camera usage / reference thread
I bought the Junsun V1 head unit but my Kia Ceed JD had a OEM nav unit which isn't directly compatible to Junsun V1. So I re-wired the wiring harness based on the pins description of my original OEM navigation unit. I'm only modifying the wiring...
forum.xda-developers.com
The only thing that I could compare to (between old and new HUs) is the canbus connectors. Rest cannot be compared as they're all different.
Oh well..
Anyways, the current Mekede I have has Radio chip NX6686. My old Dasaita PX5 also has a NX6686. However, the radio reception is absolutely trash in the new one. I dont listen to radio that often (I can resort to streaming radio) but my dad takes the car occasionally and he's already complained about it
Your experience on the harness rewiring is pretty intense!
Update: Turns out my Antenna connector was a tad loose and I had to do a re-connect. The radio reception is all good now
