GNA 10, NMEA 2000 Multi-Function Adapter
Use the Garmin GNA 10 to connect a jog lever to our Reactor 40 autopilots1 on displacement hull boats. A jog lever is a rugged and simple steering control for work boats or trawlers. Adjust heading hold with the jog lever by pressing it right or left, or put the autopilot into the new Power Steering mode to move the rudder without autopilot guidance. The GNA 10 can also optionally connect to a button and LED light to allow switching between heading hold and standby2. Garmin does not supply the jog lever, button or LED light.
