Someone a couple months ago posted the website for the "pathintosh" A guy took a Pathfinder and put and Macintosh docking bay in the cargo area just for playing MP3s, had a wireless system to transfer the sound file s from inside his house to the truck and an external remote for the thing for tailgating. among other things. not sure if he had DVD or GPS though. Was a neat setup though I prpbly spent half an hour looking at his pics and reading his write up.
