The GMR 18 HD transmits data over the Garmin Marine Network, a 100-megabit plug-and-play proprietary network that gives you the ability to expand your boats system as needed. Once connected to the network, you can use any network-compatible Garmin chartplotter as your radar screen. And as an aid to locational awareness, you can overlay the GMR 18 HD radar image on the chartplotter's map page.
