What brand is the camera? I have to hold my ON button when I turn it on and a menu pops up that allows you to change the orientation of the picture so it looks correct on the screen.
You would probably have to change the monitor and the back camera to get color. If the system is 15 years old, you will also end up snaking a new wire from the back of the coach to the monitor up front.
