The 2000 is not the same system as the 04 and on. With my o5 you have to use a GM computer interface to use an aftermarket Stereo. This will screw with alot of other car features like door chimes and steering wheel controls. I ended up having to hard wire some wires and bypassing others to get everything to work like it should. ( part of that was because I bought the $39 interface insted of the $200 interface but at the time no one sold the Interface for my application)


yeah that damn system all runs from the factory stereo, i had this same problem in my monte carlo.... good job GM
