When I turn on my Rider 400, the background screen of the world map appears with the options for quick settings, zoom in/out, and Menu. Then the screen goes black, the those options appear without the background, then black. Occasionally it almost brings up a map. The triangle appears, but no location data, then black screen, Repeat. Holding down the power button to reset doesn't work. I hear the drums, and see the status bar loading, but then it goes back to the listed problem.
unfortunately, I've just stated a trip and can't connect to a computer, not that I could get that to work anyway because the myconnect program doesn't work on my Mac. It starts to load, then the system says that it's not responding.
