Sharing User Data (Routes/Waypoints/Tracks) between Garmin ECHOMAP Plus 70/90 devices
You can synchronize and share waypoints, tracks, and routes with other ECHOMAP Plus 70/90 devices connected via Garmin Marine Network Cable (Ethernet) automatically.
NOTICE! Before you synchronize the user data across the network, you should backup your user data to prevent possible data loss. See Backing Up Data to a Computer.
To enable User Data Sharing select Nav Info>Manage Data>User Data Sharing>On
Once User Data Sharing is set to On, all data between the devices on the network will be merged. When a change is made to a waypoint, track, or route on one chartplotter, that data is synchronized automatically across all chartplotters on the Ethernet network.
