inReach Features
Messaging, tracking, and SOS functions require an active satellite subscription. Always test your device before you use it outdoors.
Ensure you have a clear view of the sky when using the messaging, tracking, and SOS functions, because these features require satellite access to operate properly.
To get the most out of your GPSMAP® 66i device, you should activate it. Activating the device allows you to use inReach® features, including messaging, SOS, tracking, and inReach Weather.
