Rear view camera non Corvette related



It already has the factory Navigation along with 2 other DVD screens. All oem from factory. What do I need to make this work? Anyone has any experience with it? Do I need a backup camera interface etc?
Any help would be greatly appreciated.
Sorry for the offtopic mods. You can move it to Offtopic if its necessary but I know what kind of help I will get there
I got a camera from him for my '07 Avalanche and he's big on the Avalanche forum(http://www.chevyavalanchefanclub.com/cafcna/index.php), but should be able to get you pointed in the right direction.




Check out this thread. He has an '07 but it may be the same. He used an aftermarket camera with IR LEDS.
