2000 Buick lesabre

I had a customer come in today with this vehicle and he wanted to have a add on cd changer installaed to the factory radio. When I pulled the radio out it did not have any wires behind it. When you slid it into the opening it would plug into a printed circuit board. I was wondering if this was some sort of databuss system or what? If anyone has seen this before please shed some light on it for me. Thanks in advance.Brian

"all electronic equipment runs off of smoke, once you let it out, it stops working"

hey, i was checking old posts and came across this. Scosche makes the adapters now for the lock and dock GM radios. Here is the deal with these radios. They are completely controlled by the computer. i am assuming its a cassette player only in the buick? if it has the cassette and cd combo, you cant put in a cd changer, perhaps an after market FM modulated one would work. The factory changer in this vechicle even works through a computer. It has only 7 wires. 3 for signal, two for the computer, and two for power. The New GMs have a two wire data bus that runs throughout the whole car. So everything is controlled by it. If you have the changer, and tell the radio you want to play a cd, the radio communicates that to the cars computer, which then communicates with the changer. Is that dumb or what? I have a 2000 bonneville, its the same car. I bought the factory service manuals for it and it has all the diagrams there. I can scan some pages if you want it, but its really not worth getting into. Good luck.

As I understand it, Blitz says they will not be making interfaces for the Class 2 GM vehicles.Best Regards,
