I recently purchased a 2018 Foretravel Realm and the 360 camera view worked well when I got it. During the first outing with the coach a few weeks ago, I noticed the 360 degree view stopped working after being parked for a few days (grandchildren could have played with the settings but engine was off so no power). All other camera views (left, right, front, and rear) show up on the monitor except the 360 view. I have fiddled with very button and menu on the display but cannot get the 360 view. I have taken photos of the display. I believe camera 4 is the 360 degree view. I have read the Camos manual but it was not much help. Any assistance is greatly appreciated.
You best bet would be to contact FT.
This seems to be the manufacturer of the system. Perhaps you can give them a call.

Total Vision makes the pan and tilt rear camera. Camus makes the 360 degree camera view.
