I went the the coach this morning started it up, everything 
Seemed fine ....then turned on the rear view camera
NOTHING
The screen said something like NO connection, lots of lines
Across screen

Any ideas where to start looking for the problem???

there are only two places it has connections. at the monitor and at the camera itself. both not hard to get at. it is one continuous cable from the front monitor to the rear camera.
