For my next trick...

I just ordered one of these from eBay: http://www.chinavasion.com/product_i...etooth-camera/

It comes preloaded with IGO mapping software: http://en.wikipedia.org/wiki/IGO_%28software%29 The eBay seller loads the mapping package onto it. We emailed back and forth a few times, as he answered a few questions.

The wireless camera is powered by the backup lights, and when it comes alive, the GPS screen switches itself to backup cam mode. I plan on putting my camera on the roof rack, so it'll see the world from 6 feet up. My rear floodlights are already up there, and a handy source of power.

The all-in-one unit will replace my Garmin Nuvi 1300 that's an almost HUD up on the dash. I didn't want to add another monitor somewhere for a backup cam, neither did I want to swap out the feature packed Jeep mirror for a mirror/monitor. I also didn't want to deal with running a camera cable, so the wireless cam will be great.
