thanks and your welcome.
but basically regardless of the head unit, its all about the wires, im not positive but i think you can do it with all head units. its just a matter of getting the wires and hooking it up, for mine i didnt want to spend the money because i dont have onstar anymore and never used the steering wheel controls, so i didnt get either one.
