Cadillac Escalade, EXT and ESV Forum - 1999 - 2006 Discussion, New escalade audio question in Cadillac Escalade Forums; Hey everyone.
Just bought a 2005 Escalade with 20" stock chrome, white diamond with 58k miles on it for 23k.
As for connecting into the factory RSE, you need to take it down by unscrewing the 3 bolts above where the screen folds up. There is then a push pin that you can just pull down. Then the whole unit can be slid towards the drivers side and can be unplugged and completely removed. After the cable from the truck is unplugged there are still 2 plugs in the back of the dvd player. One goes to the screen and the other goes to the aux input. You want the one that goes to the screen. the dark blue wire in this harness is the video +. Strip the end off of an rca and tap the positive wire into the dark blue one. then connect the negative wire to the chassis of the dvd player. To do this i just slightly unscrewed one of the screws and slid a "U" connector behind it. then just run the rca up to the nav/tv box. I was able to fish the cable from the opening for the dvd player to the drivers door above the head liner. I then took it down the b pillar and along the kick panel up to where i put the nav tool. I really should have taken pictures, but my damn camera doesn't work anymore.
