I have a 99 deville with an aftermarket stereo. First I would like to know how to find out if there was a bose or non bose system? Second I do not have the stock radio. Is there any way around not using the stock radio and stopping the annoying sleep mode? I already know special harnesses will not work including the gmrc 03. Any help thanks its driving me crazy. My next fear is the door locks won't work with the key being as though my drivers side stopped working a week ago.
