    Hello. I am asking for help in solving the problem. I would like to install Chinese android radio in A6C5. Radio 2 din in exchange for the original audi 2 din radio. ISO plugs, plugged in, power on pins 4 and 8. The radio turns on, charges Android, the final screen turns on, but after a while it goes out. The radio turns off and cannot be started. Only after pressing the reset button the radio restarts. Where could the problem be? Somewhere, maybe I should connect additional power supply?

    Power is usually on 4 and 7 +, on pin 8 minus.
    It is often the case that pins 4 and 7 are reversed depending on the radio model.
    Put the ignition switch on, start the radio and short-circuit for a test pins 4 and 7 in the ISO power connector, check if it helps, if not, the radio is somewhere.

    Screen goes gray or goes blank?

    According to the description, it is to be connected:
    A4 - + 12V fixed
    A7 - ACC + 12V after the ignition switch
    A8 - ground

    You connected so?
    Take a picture of the front panel.
    What is Android installed?

    I have the same problem, I dragged the cables straight from the battery and once it fires up ok and another 10 minutes a tragedy fires, I think maybe a software change would change something, maybe the fault is that I do not have a CAN module but it is not possible to buy my model. Help !!!

    Radio Erisin ES7826s

    Model:
    px5 (1024x600)

    Android version
    8.0.0

    MCU version:

    Added after 49 [minutes]:

    "lm2_PX5_8.0_ota (20190105)"
    I have updated such software, there is also an option that I updated it incorrectly because I inserted the card, a message popped up and pressed install and everything or maybe something else?

    You need to get a new Operating System and phoenixcard file to upload OS and new MCU. Write to the seller to have him send it to you.

    Yes. I already pulled out that radio and put on a watch. But I connected the battery at home and it turned out that everything works as it should. It turned out that the weight must be from - the battery cannot be standard from the car or the body. Write if it worked for you, I had a match with this half of the year :)

    I know it is over time, but in these cars the radio is turned on via the CAN bus. If the radio is dedicated to your car, a small module for connecting the CAN bus should be included with it.

    That's right, FACTORY. Others have nothing to do with it.

    I solved the case, the ground cable (-) had to be straight from the battery, I figured it out only when I pulled out the radio and connected it to the battery in the room. Why did the factory cube not work? You will not understand the Chinese :)

    Not completely,
    - as not on the Can module, steering wheel control will not work
    - the radio is also turned on and off after Can.

    If the car does not have Can, it is logical that it will not connect, because there is no what. My answer concerned a specific statement.
    I don't understand why are you screaming?
