Here's a view of all three screens.  We initially interfaced with their factory backup camera, but the picture wasn't so great, so we later interfaced with a composite to RGB adapter for a nicer picture.  The interface piece was far from "plug and play", and took quite a bit of tweaking to get the picture in the dash to look good.  The end result was good though, and we're thankful that Jackie and Michael were really patient while we sorted out a poorly engineered piece of equipment.  Whew!  We prefer quality stuff for our customers, less headaches for everyone involved!  (Plus, years of troublefree use makes for happy customers who get more for their money!)
