While Navigon has exited the North America market as far as PND devices are concerned, they are not completely closing up shop with respect to other types of Navigation. Available now you can pickup the Navigon iPhone app and get most of the Navigon experience youre familiar with, on your iPhone. Weve taken a few trips with the iPhone using it in Maine, Los Angeles, and points between to give the app a workout.

And for the most part we are pretty impressed:
