I'v seen some general discussions on front facing cameras, but after a trip to the dealership they couldn't answer any of my specific questions on my 2011 with Microsoft Sync. 1. Is the Nav tv upgrade (or similar product) compatible with the MS Sync? 2. I wanted to install a forward facing camera. Are there any camera systems that work? Or are there ones I need to avoid. 3. Has anyone tried installing a rear view camera on a trailer/link it to their MS Sync? 4. The auto lay feature in MS Sync is disabled, and it is disabled my phone (galaxy s7) but every time I turn on the truck it stars playing the last song/podcast even when the truck is on the XM radio. Any help would be greatly appreciated.
