I am looking for how to do a hard reset of the Navi. If you open the plastic box in the trunk you can see a small hole in the GPS box. I opened up the box and see a small white button that looks like a reset button. When I put it back together and turn on the wing depressing that button only gets you to the debug screens that you can switch through by pressing the menu button. There are a lot of debug screens. I held the button down for 10, 30 and more seconds and no hard reset.
