Hello everyone, I searched a lot in the forum but I did not find an answer, I will explain to you, I bought an android radio brand Atoto and crux interface for ram 2008 with standard amplifier, all the radio turns on, but to make you hear the audio (turn on the amplifier) ​​I have to turn the truck off and on again, and the audio is heard, it also happens that when I open the door with the engine off, the audio stops and the radio remains on, everything turns off only in the moment I remove the key, but when I go to turn on the same problem, the radio turns on but the audio doesn't .. I have to turn the key and turn it back on, ... any ideas?
