My truck is a 08 LT1 package, the truck the 6 disc came out of is a 07.5 LT1 package. It has a 6 disc stock, mine is single, can I just swap it straight across?
I think you have to have someone with a Tech II relearn the VIN in it after you have it installed. If the truck it came from also had Bose, it might need more stuff done to it. I'm by no means an expert though.
