Creating a Garmin Track Map
If anyone is interested in how to show a track or even multiple tracks with different colors on a garmin, I found it can be done with the following programs:
Use Basecamp to create a list with one or more tracks and save as a gpx file.
Use IMGfromGPX to convert the gpx file to a map.
Use JaVaWa GMTK to load the map into Mapsource.
Use Mapsource to load the map into the gps.
