How to use a Garmin Sat-Nav

Garmin Sat-Navs (Satellite Navigation) devices use GPS (Global Positioning System) satellites to triangulate a position. The position is then superimposed onto a map that’s displayed on the screen. Points of Interest (POIs) like gas stations and hotels also can be generated. The devices create navigation routes from your current position to a POI or other location. Using a Garmin Sat-Nav can be accomplished by following some routine steps, including finding your destination and following your route.
