Are there any mapping programs for Linux? I found http://www.gnomad-mapping.com, but they don't seem to have anything I can download yet. I just want something I can hook my Garmin GPS up to, and have it display a continuously updating map with my position on it. Even better, if I could upload maps using it then I wouldn't have to use Garmin's windows software. WINE chokes on anything related to a serial port. Jay
