Hello all! I have a 2005 Expedition Eddie Bauer that has the nav, 6 disc changer and the dvd player in the roof. A friend gifted me a radio that from the part number comes from a 2003 - 2006 Navigator. It has a WAYYY bigger screen and I would like to use it if possible. It comes from the same gen I thought they would be interchangeable. Would there be any reason why the swap wouldn't work? (New radio won't control the DVD etc) If it did work however I plan to buy a wiring harness so I don't have to cut up my trucks wiring and was going to graft that to the Navigator wiring harness. I was wondering if anyone knows this wiring diagram for the Navigator radio. I would think the harness to put an aftermarket radio would cover me for the Expedition side of the install. My stock Expedition radio And the Navigator radio Any help would be appreciated
