I haven't drive my car for a few weeks and the battery is gone, i have to find someone to start my car for me, after that, my audio function is disappeared but touchscreen is working fine also the air conditioning system is working. I have find some garage to check my fuses and it's all fine. Then, I bought a new audio unit for my car and fitted on, the problem is still there. and now i don't know what should i do......
btw, i can put tape in there, but it's now playing, I think that's mean the audio unit have power supply.
Can somebody help me here? thx a lot mates....
