I don’t know if there is a connection between the two, but since my car battery went off I can’t save settings in my multimedia. The radio Chanel’s are set to USA instead of China so I can’t set Chanel’s. The navigation app won’t save the Exe path ecualizar and etc. Every time I turn off my car the settings are restarted. Pls can anyone help me solve this problem? I think the multimedia system is avox 80152a something.
