Cadillac Repair: radio, ac delco, cadillac deville

Question
i have a 1999 cadillac deville which has a stereo unit with only a  cassette player. I am trying to install the new unit which has a cd player. this unit is not an aftermarket but it is an orignal ac delco unit, the ones that come standard in the 1999 devilles already .i had the old stereo taken out and put this new unit in but no sound comes to the speakers. what could this be from? also i already know that if your original stereo is a delco you cant install a bose system.

Answer
Hi,

Well, if the stereo with the tape deck worked and when the CD was installed all fuses are good and all connectors are plugged in, there is only one answer. There is an internal problem with the cd unit.
Sounds like you have to either take the cd back to where you got it for an exchange or you will have to send the unit for repair.
