i just bought my first audi on monday, 1993 90. the kid i bought its from said the radio had stopped working. i thought nothing of it becuase i had another headunit that i planned on putting in anyway. the unit that came with the car was a sony and it didnt work, i could put a cd in and it would spit it out. it would not turn on or anythi ng more then that. the unit i planned on putting in was also a sony so i didnt bother rewiring the harness becuase the plug fit both units. and the same thing happened with my headunit, i could put a cd in and it would spit it out when i pushed the eject button. but yet agian nothing more happened.i then took the wiring harness out and undid all the crimps that connected the plug from the back of the radio to the car wire harness and re-crimped them all again. and the same thing happened, could put a cd in and take it out but nothing more. the unit is getting power if it takes the cd and ejects it. im dumbfounded



any body have any ideas on what the issue could be?
