I just bought GM Part # 25834072, it's a factory nav out of an '08 Yukon. I want to put it in my '07 Silverado LT. I have the regular XM radio, no DVD or Bose or any of that stuff. I'm guessing I will need a wiring harness, and some kind of brown speed wire/plug? That's what I have gathered from other forums and threads. If anyone can help me with part numbers and installation tips it would be much appreciated.

 

Alright, after doing a little more research, it looks like I need these things:

Any 4-channel amp
VSS Voice Harness
PAC OEM-2 - this lets me hook up the amp?

Am I missing anything here? I saw something in a post about a speed wire that needed to be hooked up but I can't find much on it.

 

Will this cover me for the VSS voice harness and the speed wire? I remember someone saying it was brown, and I see a brown wire here.

yea that seems to be it
as far as parts

 

well i'm about to do the same swap on an '07 silverado with no bose and regular radio, but i'm planning on buying the whole set of wires on ebay, well i saw the whole set there, they say that this is all you need to hook up the nav sis, but i have to remove the "theftlock" first following the instructions that shawnvw posted on another thread, i will post the results when i'm done wtih it.
