I have a 2012 Dodge Ram 3500 with factory back-up camera, rear seat video and RHR navi head unit.
I installed the CHR-550 today, I have a couple questions.

I can get the back-up camera to operate when the shifter is in reverse and also by selection the reverse camera option on the tv menu. But when on the am/fm/sat screen the back-up camera will not activate when pushing the power button 2 times.
Also when I have a Iphone 3 or Ipad I can watch video on the dash head unit but I can't get the video to play on the rear seat tv? When I play a dvd it plays both in the dash and the rear tv, but just won't work on the rear tv when played thru the Iphone/Ipod.

Any help or info would be great.
