Used my iPhone with a window mount at dash top level and the program MotionX a few times. It was pretty good. Any more its just to easy to ask siri, make sure it's got the correct destination, then just put it back in my shirt pocket, and listen to the directions.

Most of the time, I do the Porsche thing and...Pull up maps on my computer and make sure I know where the heck I'm going before I ever get in the car. To me, just following NAV all the time is like stopping and asking for directions, negative man card points unless she sounds really sexy.

I don't remember anyone's phone number though.
