VERY COOL!check out http://navdy.com. Navdy plugs into your ODB, provides google map navigation, with a simplified display, telephone linking, and shows any alert you've set your phone to show, all in a heads-up display. I may get one for my current car (my Garmin pisses me off because it's so inept) and move it to the Elio when it arrives. There's a possibility Elio may offer it as an option.
