Next you punch in the starting location and ending location so that it will map your route and click start. You can progress through the directions with the arrows at the top and if you notice the find my location button at yhe bottom left changes from blue to gray. If you tap that button, Google Maps will bring your current location back to the center and hold it there until you either deactivate it by tapping the button again or by veiwing the next step in the directions. I'm pretty sure that this feature was in the original release of the 2.0 firmware but I just realized that it did this a few days ago while I was out of town and needed the to use the GPS heavily.
