Here is a very short vid at VIR made with my iphone4S mounted on a tri pod in the rear seat - center of the E92. I have no external GPS, using only the iphone. This was a test to see if the phone would be able to function on its own. Please excuse the quality of the picture as I had difficulty loading it into youtube.
