The Garmin GNA 10 Jog Lever Adapter bridges a jog lever to a Reactor 40 autopilot on displacement hull powerboats, giving workboat and trawler operators a direct, no-fuss steering interface. Push the lever port or starboard to adjust heading hold, or switch into Power Steering mode to move the rudder directly without autopilot input. An optional button and LED can be wired in to toggle between heading hold and standby. The GNA 10 also interfaces a Reactor 40 with Jastram digital steering controls. Note that the jog lever, button, and LED are not included and must be sourced separately; a compatible Garmin autopilot and Garmin display are both required. This adapter is designed exclusively for displacement hull powerboats and is not compatible with planing hull vessels or sailboats.
