I've just had my truck repaired (to the tune of $1,200). The battery had to be disconnected and now theradio won't work. In order to get the code required to get the radio to work I've been asked by the Chevy dealer to give them $45. I am not about to do that, but as I bought the truck used about 5 years ago, I never did have the original code. Even Chevrolet wasn't any help on the phone. Does anyone have the code I need for this make and year? Thank you.
