Nav owner here, very interested in doing this. I basically listen to my iPhone all the time in the car, so why not have an iPad in there 24/7 with a data plan. Lots of good info in the links already posted, but not so much for navigation owners...
My screen keeps loosing pixels and I would rather do this than replace it and/or buy a new $200 navigation disk...
Loosing regular (ancient) radio capability wouldn't phase me. Between my own library and Pandora, I would be set!
