MY '91 had been sitting for a month and the trunk had flooded. When I tried to play the cd, i got an ERR message. I looked in the trunk and there was a lot of condensation of the cd unit. I drain the trunk and let it dry out and then the radio head didnt recognize the cd unit and I couldnt unload the deck of its cd's. The radio worked. I unplugged the deck and checked to see if it was getting voltage on the acc and logic pins from the radio. Now the radio wont turn on. Could I have somehow activated the anti theft on the radio and if so does anyone know how to reactivate it without going to the dealer?
