went ona road trip today and for the first time i used the gps on the phone for directions. Hooked it up to the usb port in the car for charging really and then i discovered i was able to play music through the car radio like i do from my usb stick. all of a sudden a voice came over the radio with instructions to turn. Didn't realize it at the time but the phone was playing it gps directions through the car audio connection. wow what a surprise. i loved it
