Hi all, recently radio has stopped working on mtce head unit doesn't want to scan. I have tried factory reset, flashing alternate roms and trying a few mcu. It is a xcr2 and currently android 9. I have also tried disabling and re-enabling radio and changing from Australia to China and back again. Also checked cables are secure in head unit. Stating to suspect something hardware has failed, is there any other suggestions I might try.
Sounds like a hardware issue

I was recommended by the vendor to do a system update to 4.4.4 and to update the MCU aswell. He provided the files. After I updated the MCU I immediately lost all audio. I cannot hear music, cannot hear GPS, cannot hear DVD's. Adjusting volume does nothing. I disconnected the head unit from power to reset it but did not help. I then performed a factory reset and to my surprise this also did not help.
What happened and how can I fix?

Have you tried wiping the dalvik cache partition?
did you play with the unit Hardware ? because it happen to me and I forgot to connect one of the cables. so you check that.
also if you are sure 100% that the problem from Software , so try the following:
1) Go to Bluetooth and connect your phone and make call check the sound is it working or not.
2) Go to Factory settings and check every option carefully try to play with it.
3) Last solution try to find the Original MCU ( maybe by contact the manufacturing ) or try to find MCU version that is 100% compatible with yours.
Forgive me if these questions have already been answered, if they have, i have been unable to find them.
My android Head Unit works as expected for about a month and then it starts having System UI issues. After the first 'Unfortunately System UI has Stopped' message, a simple hard reset clears the error for a day or two, this process can be repeated 5 or 6 times until the error message displays even after the re-boot (see video)

(Please add WWW etc and paste into browser i am unable to post links and cannot stop it auto adding the URL wrap)
I have previously been able to enter a recovery menu and perform a factory wipe and reset which stopped the message occurring. However, i do not know how i got that menu up and cannot repeat it. so this is my first question:
What sequence of reset pin-hole button presses do i need to do to access the recovery menu?
my second question is what can i do to prevent the System UI from failing?
Incase it makes any difference I believe the head unit that I recieved is acctually a PB86MTVP (I wanted Android 7 but the unit is running 6.1)
I'd contact Xtrons directly, and let them know about the problem, and ask for a system firmware update.
Best of luck!
I have done, and they have sent me updates which do not install. I think because i have a different unit than i ordered but they say i have the right unit and the right update file...
so i found this on an Xtrons forum thread and tried it and it installed! lets hope it was a newer version and not an older one and it fixes the issue. I'll report back in a month or so.

Sorry for bringing up and old post, i've seen one of these now slightly older Xtrons PA87MTVP going on eBay - is it worth buying? How is this head unit working for you? What are your like and dislikes of this unit? Thanks
Hi guys

And then i could ever open again.

Same here, after resetting the radio to factory defaults the radio app works again, but as soon as I do a search the app won't start again.
my radio is a YT9213AJ_00011_VOL001_20200330 XY Auto: 3.2 ( 8227L )
Did you find a solution ?
radio app problem
i have the exact same problem. radio crashed while searching for stations and now no longer starts. I launch the app, a black screen and then go back to the home page.
I tried with some reset but nothing.
is there a total factory reset like for mobiles?
were you able to solve the problem?
Factory Reset will solve the problem.
Hello Friends
I've had issues with this headunit for a long time. Last week, side buttons started not working. After several attempts, I managed to "factory reset" which it does not wipe, just reinstalls without erasing anything. Sometimes it works like normal but the majority of the week it doesn't.
I've tried several methods and I realized that the top status bar was not visible, but when I've been able to activate it, everything is back to normal, including the side buttons.
So I wonder if you can help me saving some money, because it would be pretty sad to get rid of this radio and get another that might have the same issues.
I hope you can help me

Please note that I gave up on this unit (MTCD PX5 units are so much nicer...). I will try to update this post (however infrequently) with information that may appear in this thread or come my way by other means, but I will not seek information...

Thank you SO MUCH! I will follow all the procedure and let y'all know!
Have a wonderful day, Mr. Jones!
Edit:
I finally solved it, so in case anyone else has the same issue, here it goes.
Hi. If you still cannot downgrade, I have a solution that worked for me.
Look on the head unit harness for a cable that is marked Key 1.
With the radio off, put a flash drive with your update file in the required folder. Connect that Key 1 cable to ground in your car, turn on your radio and reset your radio (mine has a reset pinhole). When the radio restarts, it will force flash the firmware. After flashing, remove the ground connection and the flash drive.
Original post:
So, against my better judgement, I decided to update my TS18.1.1 head unit to TS18.2.2 firmware by modifying the file names, which worked, and almost everything worked properly, but now whenever I start listening to radio stations, a different music app like Pandora will start on it's own playing music. I have reset and reinstalled everything like four times already and have not found a solution so I guess my only option is to go back to T18.1.1 firmware.
The problem is that after renaming TS18.1.1 software and trying to install, the head unit reboots, starts installation and stops. The radio reboots and the firmware is not installed.
The 2.2 firmware is from February 2023 and the 1.1 is from December 2022. Maybe this is why I can't roll back.
So my question is, is there any way of forcing the older firmware into the radio? Or will I have to wait inter a newer 1.1 firmware, if it's ever released to go back?
Hi, if you have root access and seeing all folders on mounted device disk, delete folder named "cache" if you have it. then restart and see if helps, and try to update system again with ver. 2

Thanks for the suggestion but I do not have root. Still, I did find the solution.
