Greetings. I own a 2007 Suburban that is still in great shape with factory Bose stereo and the roof DVD system.

I hate to admit it but I'm getting to a point I REALLY need a backup camera for parking lots. To get around the problem I have been parking far away from everyone so I can just pull out forward but I decided since
I plan to keep the beast for a few more years (just hit 150K miles) I thought I would invest some money and add a camera.

So my question is: Does anyone have a suggestion for a stereo that

#1: Has backup camera ability
#2: GPS (which I don't have)
#3: The ability to play DVD's on the factory overhead system for my granddaughter.

Any help would be appreciated.
