The Garmin GRA10 Rudder Angle NMEA 2000 Adapter turns your existing marine dashboard into a connected digital network by converting rudder-angle data to a NMEA 2000 signal. It’s designed for boaters who want a straightforward upgrade path that preserves current gauges while expanding networked navigation.
-
Conversion to NMEA 2000: Takes data from your rudder-angle sensor and outputs a NMEA 2000 signal to join Garmin displays on the network.
-
Garmin ecosystem compatibility: Works with Garmin’s ecosystem, including the GMI 10 Digital Marine display, to bring older dashboards into the digital age.
-
Upgrade path from analog to digital: Preserves your existing gauges while unlocking networked data for real-time navigation insights.
-
Network expansion without replacement: Add more data visibility across your boat’s network without replacing existing equipment.
-
Compact, marine-grade design: Small form factor designed for marine environments and easy installation.
-
Key specifications: Dimensions 31/32" x 43/64" x 3 3/32" (24.7 x 17.0 x 78.6 mm); total cable length 16 ft (4.9 m); operating temperature 5°F to 158°F (-15°C to 70°C); power input 9–16 Vdc from the NMEA 2000 bus; power usage max 1.1 W; NMEA 2000 LEN 2 (100 mA).
-
Rudder-angle sensor required: Rudder-angle sensor not included — the adapter requires your existing rudder-angle sensor.
View rudder-angle data on compatible Garmin displays connected to the NMEA 2000 bus, delivering real-time navigation insight without a full equipment overhaul. The GRA10 combines a compact, reliable design with straightforward installation, making it a practical upgrade for expanding marine networks.
