Well, I will answer my own question with this.
It looks like its only a matter of time that dash GPS units will incorporate
a video input
to allow a back up camera to be installed. Giving you a wide angle view on
the GPS screen.
They can be wired to the back up light circut and can even be wireless to
the camera.

Cool stuff!

I have a syncro buddy who really could have used this on a desert trip
recently where he almost backed off the
side of a road trying to take a new line on a climb.

Doug, with the traveling and tourism work that I do from my vanagon,
the GPS (in my case a tomtom) is a permanent fixture. They are the
best thing that ever happened to traveling on the road. I use mine
about six times a day when I'm on the road. I never consult or print
out maps, all I need is the name of the town or the address. Even
tells me when I'm going to arrive.
