I have the P 1.1.1, crashed, and repaired from dealer. He said alls good, but I just had yellow flashing light. Tried lots, then took it apart to find gps not connected, so that should be it. No dice. Still fast flashing yellow. Software shows gps and compass seem connected (changing values when software connected). Anything else I can do? Don't want to pay shipping again for something I could do. Thanks to all that can help.
