I have a 2002 w/Nav and JBL audio system. Radio worked fine one day and no audio, not even the antenna) worked the next. I have replaced the factory amp and Nav screen without any change.
I noticed that the radio/tape deck buttons weren’t working at all, so I replaced that. After replacing the radio/tape deck everything will turn on, antenna goes up and down, and all the buttons seem to work, but there’s ZERO sound.
I have checked for power, grounds, and continuity. All seem good. One wire in question is the blk/red wire from the radio to the amp labeled “amp” I’m not sure if it’s supposed to have power or not.?.? I use a jumper and have it 12v and all of a sudden I had music coming out of the speakers full blast!, but the volume control was inoperable. Not sure if I bypassed it or what.
So, I’m not sure if my radio is bad and not sending a signal to the amp, or if the amp is bad and not turning on.?.?.
All parts that I bought were used of course. Any and all help is very much appreciated!!!
