2006 STS V8 1SF RWD
How would I go about removing the HU in my 2004 CTS? I need to get the ID number on the back so the dealer that sold me the car can order a replacement unit. The 6-disc changer does not work, you get "CD Mech Error" when you press "load." I never turned the stereo on during the test drive, guess that wasn't on my priority list when buying the car...He has agreed to purchase a new unit (probably used) and have it programmed on his buck, I just have to get him the ID number which I am told is on the back of the unit and the only way to get it is either manually or with a TechII programmed with Cadillac software. I figure I've removed tons of HU's just need to know where to start with this one. Thanks in advance!
