Garmin GPSMAP 66i, GPS Handheld and Satellite Communicator, Featuring TopoActive Mapping and inReach Technology

Garmin GPSMAP 66i combines a proven handheld GPS navigator with inReach satellite communication — navigation for reaching your destination and satellite messaging when you need to communicate from remote terrain where cellular networks don't reach. The 66i is built for expeditions in genuine wilderness, where two-way satellite communication changes the risk profile of the entire trip.

GPS Navigation and Satellite Messaging in One Unit

The GPS platform delivers the reliable GPSMAP format: dual-constellation GPS and GLONASS reception, TopoActive topographic mapping, waypoints, and track recording on a 3-inch sunlight-readable color display. The inReach layer runs over the Iridium satellite network — the same global coverage system used by government and military field operations. A monthly satellite subscription is required for messaging features; the SOS function activates emergency response through the GEOS 24/7 center regardless of subscription status. For mountaineers and remote wilderness travelers, that emergency access changes the math on how far from help you can operate safely.

• Dual GPS and GLONASS — reliable position lock in dense cover and canyon terrain
• TopoActive mapping — preloaded topo maps with routable trails and roads
• inReach two-way messaging — Iridium satellite network with global coverage
• SOS to GEOS 24/7 emergency response — active regardless of subscription status
• AA battery power — days of field operation without charging infrastructure

For mountaineers, remote hunters, and backcountry travelers whose trips extend beyond cellular coverage, the GPSMAP 66i provides both navigation and communication confidence in a single rugged unit that runs on standard AA batteries.
