Ever since I purchased the Navigon GPS application for my iPhone, I find myself leaving it on the "Show Map" screen for it's very helpful speed limit warnings, and upcoming roads, whether I need "navigation" or not. I have a little car mount with a charger/headphone adapter thingy. So battery life is not an issue for me when driving with the map screen on. So what I do is I start a song on the iPod, then start up Navigon GPS, and have the speed warnings as well as the turn by turn route directions (when I need them) come on over the music. Does anyone else do this with their GPS? (Whether its iPhone, Garmin, TomTom, etc). I feel like I am the only one, haha, but hey, It also makes the car feel more high tech too (especially with speed limit warnings, as well as the route directions coming over the speaker for the car, rather than the one in the iPhone).
