Take a "big sweep" of your surroundings

Integrate with any network-compatible Garmin chartplotter

Any network-compatible Garmin chartplotter can double as your radar screen. And as an aid to locational awareness, the GMR 406 radar image can be overlaid on the Garmin network's moving map cartography display. The on-screen display can also be split, allowing for a simultaneous view of mapping alongside the standard radar picture.

Easily Connect to Garmin Marine Network

The GMR 406 communicates with the Garmin Marine Network through a waterproof 100-megabit plug-and-play proprietary network which gives you the ability to expand your boats system as needed. You can connect a GPS antenna and one remote network sensor (like the GMR 406) directly to a multifunctional display. Or, with the addition of the GMS 10 Network Port Expander, you can connect multiple displays and network sensors to the same network.
