Garmin User Data Limitation for Networked Devices

Garmin chartplotters and fishfinders have the ability to store a large amount of user data, like waypoints, routes and tracks, however, there are limitations. Networking multiple devices together using the Garmin Marine Network will not increase the user data limits. To see the user data limits for a specific device, visit the devices Specs page at Garmin.com.
