Is there any way to put a navigation system/video screen from a different GM vehicle into my Silverado 2500HD? If so what year vehicle should it come from?
Thanks

Check ebay, they normally list which vehicles thier equipment is compatable with. Either that or check with your dealer.

If your truck is 2003 and newer then yes, if not no the gm navigation will not work with the 2002 and older trucks, I tried but you would have to replace the entire wiring harness, and all computers and required sensors. Now if yours is 2003 and newer you would also need a matching amp for the nav unit other wise you won't hear any sound.
