The Garmin GNA 10 Jog Lever Adapter connects a jog lever to Reactor 40 autopilots on displacement hull powerboats, giving workboat and trawler operators a rugged, straightforward steering interface. Press the jog lever right or left to adjust heading hold, or engage Power Steering mode to move the rudder directly without autopilot guidance. An optional button and LED light can also be wired in to switch between heading hold and standby. Note that Garmin does not supply the jog lever, button, or LED light, and the GNA 10 requires both a compatible Garmin autopilot and a Garmin display. It is designed exclusively for displacement hull powerboats and is not compatible with planing hull boats or sailboats. The GNA 10 can also interface a Reactor 40 autopilot with Jastram digital steering controls.
