Garmin GPS devices can use a number of different maps, including premium map packages that can be purchased and downloaded from the Garmin website. If you’re planning a nature outing, geocaching expedition or other trip, however, the routes and waypoints included on these Garmin-produced maps may not fully meet your needs. Using the MapSource program that ships with Garmin GPS products, you can edit the maps on your GPS device to include the places, waypoints and routes that you need for your journey. Tips Writer Bio
