A snowmobile GPS demonstration. A snowmobile trail map for Maine, New Hampshire, Vermont, New York or Pennsylvania from GPS Trailmasters will install to your Garmin GPS and overlay the existing base map that comes with your Garmin. Although this demo is for the Garmin Nuvi 52, our maps are compatible with most Garmin GPS models. Your Garmin GPS provides the turn-by-turn routing firmware so that capability must be included with your GPS. Other considerations for the Garmin you choose is the screen size, battery life and the ability to hard wire your snowmobile GPS to a 12V source. The outdoor hand held units are typically ruggedized and waterproof. The automotive units like the Nuvi 52 are more susceptible to the elements but have larger screens and cost less money. The snowmobile trail map can be downloaded instantly to your GPS or it can be shipped to you already installed on an SD card. Trails are color-coded to identify corridor trails, secondary trails and even club trails. Unique line styles are used to identify lake crossings, plowed roads, closed trails and ungroomed trails. Use the "Where To" feature to access gas, food, lodging, parking, etc. We have hundreds of trail accessible POIs built into our map. Auto route with turn-by-turn directions to your destination. See your position on the map as you ride the trail. See your track behind you as you ride. Save your tracks for later use or submit to GPS Trailmasters to be added to the map. http://www.gpstrailmasters.com
