I did a series of posts a while back on creating custom waypoint icons for compatible Garmin GPS units. If you don’t have the time or patience to make them yourself, there are several free sets of custom waypoint icons available online:
- Western Maps LLC has a set of icons (original size is 16×16 pixels; the magenta color is transparent on the GPS display):
- The Elsinga family website has sets of icons for geocaching, marine navigation, miscellaneous, and speedtraps:
- This site has IALA marine symbols:
See my original series for info on how to upload these to your Garmin GPS, and use them in the MapSource program.
