"Built for every part of the journey, the Garmin Overlander GPS All-Terrain Navigator delivers a rugged, bring-anywhere navigator that can easily switch from turn-by-turn directions for on-road navigation to topography maps for off-grid guidance in North and South America. An essential device to include with your overlanding gear, the Garmin Overlander GPS All-Terrain Navigator features integrated pitch and roll angles as well as a compass, altimeter, and barometer to help you and your vehicle navigate difficult terrain. A built-in rechargeable battery means you can even take it beyond your vehicle. Customize street navigation for the size and weight of your truck, plus alerts for upcoming bridge heights, weight limits, sharp curves, steep grades, and more. Mount your Overlander navigator anywhere with a powered magnetic mount that comes with a suction cup and 1"" RAM-ball-compatible adapter. Pair your Overlander navigator with the inReach Explorer+, inReach SE+ and inReach Mini satellite communicators (not included) for 2-way text messaging, interactive SOS, and weather forecasts. GPS, GLONASS, and Galileo support helps track in more challenging environments than GPS alone. Preloaded street maps provide turn-by-turn directions for North America and South America, as well as preloaded topography, including public land boundaries, 4X4 roads, forest service roads, waterways, trails, and other land-use data. Record your tracks and save them to your Garmin Explore account so you can review them later on any device or share them with friends.Manufacturer model #: 010-02195-00.
