here is the auxiliary input adaptor for your vehicle
I am looking for an aux inpt adapter for my bose stereo.
I have a 2003 GMC Envoy SLT (6 cd in dash changer), it has the aux/cd on the same button.
Local store is having a hard time finding this part for me.
Also wanted to know if its just plugging it in in the rear of the head unit, or does this require power of any kind o any other special installation? Ideally Id like to do it myself and I can get to the back of the head unit.
