Hi. I'm looking for a good NAV app that takes advantage of the iPad's screen size. I do have the Motion X app, but this requires a 3G connection and when I'm on the highway there's not always 3G available. I don't really want to spend the money on TomTom or Navigon because I'll just be using screen doubling with them and I'm not sure they'd look very good. I do know there is one other iPad specific app that is available, but the name escapes me and the reviews were quite poor. Anyone have insight or knowledge on how TomTom/Navigon looks on the iPad? Thanks all.
