Bernnienj, if you don't already have a backup camera, or the one you do have is no longer working, you can add or replace your camera. My old visor-mounted backup camera died and i replaced it with a TADI BROTHER'S unit
that fits over my existing rearview mirror. It's a beautiful color upgrade, the old one being black and white. Sharp, bright, amazing difference. No wires to the front of the coach. Just get power from the rear, upper marker light next
to it, and tap into the power wire to the old one up front, they talk to eachother wirelessly.
It even doubles as a rear view mirror when it's not on.
