Roam the unknown with Tread-Over land Editions, the all-terrain sat nav offers either an 8”or10"ultra bright display made for every overlanding expedition. Enjoy turn-by-turn trail navigation for traversing unpaved roads and trails plus custom street routing for the size and weight of your rig. The sat nav includes preloaded topography and iOverlander™ points of interest, so you won’t need a signal to route to the best-established, wild and dispersed camp sites. With an active satellite subscription, built-in inReach®technology offers global satellite communication, two-way text messaging, location sharing and interactive SOS. Pair your device to the Tread®app on your compatible smartphone to track up to 20 friends using the Group Ride Mobile feature, sync trip data across all devices, and plan routes with the same maps, vehicle profiles and route preferences that you have on the Tread device.
