This was on my Dads Envoy when he Bought it. The truck is an late build date 08, and had 20,000 miles on it when he bought it a few months ago, so I'm assuming the unit cant be more than a couple years old. It worked flawlessly while on his truck. I have all of the original parts ( brain, bypass module, wiring harness(not hacked), reciever that mounts by the mirror, and (2) 1 button remotes, that are very small.) The Bypass Module is for GM's. Model ASGM4. Im not sure if any other manufacturers require bypass modules. Any place will install it, or you can find the install manual and owners manual online (I have the websites). EDIT: $65 OBO for everything.
