The touchscreen combo is fully networked using the Garmin Marine Network, NMEA 2000®/NMEA 0183, J1939 and built-in ANT® connectivity, so you can build your marine system with radar, autopilot, sonar modules, instruments, sensors, FLIR cameras, FUSION-Link, VIRB camera streaming and more. Network sharing allows you to share data among all compatible units connected to the network.

Built in Wi-Fi gives you access to the free all-in-one ActiveCaptain app, so you can manage your marine experience from nearly anywhere. It creates a simple yet powerful connection between your compatible mobile device and your Garmin chartplotter, charts, maps and the boating community. Wherever you are, you’ll have unlimited access to your cartography, the ability to purchase new maps and charts and access to the Garmin Quickdraw™ Contours Community. Stay connected with smart notifications on your chartplotter screen. You can also plan a trip or prefish a lake, and ActiveCaptain will automatically sync with your chartplotter. Even get notifications for software updates, and decide when to download them on your device.

To help you gain a wind-maximizing competitive edge, your chartplotter features a prerace guidance page. It shows your virtual starting line along with data fields showing laylines, time to burn before the start and a race timer that can be synchronized across all your networked Garmin GPS products. In addition, other supported sailing features include an enhanced wind rose, heading and course-over-ground lines, set and drift, true and apparent wind data and more.

The fast, responsive 10 Hz GPS and GLONASS receiver refreshes your position and heading 10 times each second to make your movement on the screen more fluid. Now, it’s quick and easy to drop up to 5,000 accurate waypoints and find your way back to them.
