	Holux GPSport 245 is a datalogger with display suitable for cycling, walking and running.
        It can store ~200k trackpoints with limited data. The m241 and m241-bin format is
        able to automatically detect GPSport 245 data and handle the differences from Holux M-241 devices.
        Note: GP245 does not log any quality of the position.
