Hi i have 08 sierra i just bought it somebody took out original radio,and put in a navi touch screen had all the bells and whistles nothing works, took it out the wiring is a rats nest next to radio is a can bus decoder,no idea what it is. Is your factory harness completely cut up or modified?

Post some pictures up so I can see the damage. Dark green 12v switch does not deliver full 12v. Bought this from a dealership that had already replaced the radio they used it as a parts running truck for 20k and they had installed the radio with a Scosche GMLAN adaptor for a truck with onstar.

Looking at factory wiring, truck never had onstar. The door chime speaker in the LAN box shorted and was causing a draw that was killing batteries so I removed it and hard wired everything according to your notes above. Everything seems perfect, only that dark green wire separate from one that drives RF- does not deliver 12v on key on, it does deliver some voltage but not enough to turn the Alpine radio on.
