My Garmin RV660 GPS is 6 inches. There is a 7 inch, RV770. It can accept up to 4 wireless backup cameras. I mounted 1 on my truck bumper, wired to the backup light. I mounted the 2nd under the tail light on the camper, wired to the running lights. When I backup into a sight, the truck backup camera kicks in, then I just push a button on the GPS and the TT backup camera kicks in. Works Great! I can access the TT camera while driving, but the vibration causes the screen to freeze up.
