Turn your existing marine dashboard into a digital network with the Garmin GRA10 Rudder Angle NMEA 2000 Adapter. This compact, easy-to-install device takes the data from your rudder-angle sensor (not included) and converts it to a NMEA 2000 signal, so you can expand or create a network without replacing all your gear.

Key benefits include effortless integration and a seamless upgrade path. Once installed, rudder-angle data can be viewed on compatible Garmin displays connected to the NMEA 2000 network, delivering real-time navigation insight without the hassle of a full equipment overhaul. The GRA10 works with Garmin’s ecosystem, including the GMI 10 Digital Marine display, to bring your older dashboard into the digital age.
