Just purchased my 2014 JGC Overland on Friday 4/12 and found 2 issues with the 8.4AN screen
1. When I shifted into reverse, the rear camera came on as it's supposed to; however, when I shifted back into DRIVE, the camera view stayed on the screen, even though I was listening to satellite radio at the time.
2. A couple of minutes of driving around with the camera on (a view I never got to see on my 2011 JGC Overland
the screen went blue, and periodically bounced back and forth from the rearview camera to blue screen -- it cleared itself up when I shut the car off and restarted it later.
