I have a 2008 GMC Acadia with a bose system, and a rear dvd player, but it doesn't have navigation. I also have access to a 2010 GMC Acadia that has a bose system, rear dvd player, and a touchscreen navigation with a backup camera. I was wondering if it was possible to swap the head unit? I';d like to put the navigation touchscreen, and the backup camera on my 2008. Is it possible? Thanks for any help.
