Hey Guys. I need a little insight. I have a 2002 LS8 and i have been told that the stereo system including the head unit and the cd Changer is connected to the alarm system. My cd changer keeps jamming on me and i would like to change the Head Unit and put an aftermarket cd Changer in it but i don't know if its possible. I know alot of u have changed the head unit Were there any issues and is the Stereo system connected to the Alarm System?
