If you are not a member of the three View/Navion Forums (Regular, Techie, and Mods) you would do well to join.
The original camera system that is in my View appears black/white, but the monitor is, I think, a color monitor, as it has tint, color, brightness, volume (yes, sound from back there) and a couple of other adjustments. The picture on mine is quite good, more than clear enough for backing up.
