Android Head Unit issues with AUDI A3

Hi,

I recently upgraded my AUDI A3 2015 with Android Head Unit and external camera purchased through AliExpress, my reverse camera is showing black screen, although it detects the reverse mode but no image. Please help.

Hi, I think that multimedia is too weak for your car radio, but we can try to fix...
You must find a hidden menu/factory menu/admin menu (asks a pin code to get inside) where infotainment menu is and tweak settings there. If this multimedia has canbus device attached to it make sure to find correct settings for your model of car (PSA settings in hidden menu/can type/bus).

Thanks Anton, tried hidden factory settings, but could not find the right combination. Trying various options but no luck. Will share setting screens if that could help.

This loose red wire near cables harness that looks disconnected what is it for? I think you must connect it if it connector for some kind amplifier or antenna, and what is this RCA yellow jack for ?

Thanks Anton, I actually upgraded software provided by supplier, cable connections and other stuff is ok, but my device is unable to load android, I need help in flashing the *.img file provided by supplier.

Why flash, just insert old img and get back old system, then try again with updates but I suggest doing it with adb and with connection to a PC

Thanks Anton for your suggestion, device is having some hardware issue, seems USB is not working, tried connecting my phone for charging but USB did not work, so unable to connect to PC, have asked suppiler for the replacement.

I think that some hardware like gps antenna or some other hardware is not functinal and causing problems. Get a skilled technician to look motherboard and device it self. As far as peripheral ports like USB and othe ports, you can test them on your own, just unplug one by one while device is on and see if device will stabilize its self.
