The Garmin Montana 700 Rugged GPS Touchscreen Navigator features routable topographic maps, BirdsEye satellite imagery, multi-GNSS networks, and ABC sensors – altimeter, barometer, and three-axis electronic compass. GPS, GLONASS, and GALLIELO satellite networks track your position, even in difficult terrain. The Montana 700 uses a built-in rechargeable lithium-ion battery to provide up to 18 hours of runtime on a single charge. GPS Expedition Mode, a lower-power version of the network can run for more than 300 hours. If recharging is not possible, AA batteries can also power the unit. A Bluetooth connection to your phone grants access to active weather forecasts and allows you to share location, routes, waypoints and adventures through the Garmin Connect app.
