This script converts all the *.loc files in one folder into one GPX and one KML file. the KML file can be placed on a webserver and then fiewed with google maps or via google earth. Here are some usefull commands:

Upload route:

sudo gpsbabel -r -i garmin -f usb:0 -o kml -F u.kml

Tracks downloaden from Garmin:

sudo gpsbabel -t -i garmin -f usb:0 -o gpx -F tracks.gpx

Switch the Garmin off:sudo gpsbabel -i garmin,power_off -f usb:0

Best Webpage I found for creating routes for bike tours is Marengo

And now have fun.
