Garmin GNA 10 is a specially developed interface that allows you to connect a jog lever to Garmin Reactor™ 40 autopilot systems on boats with displacement hulls, such as workboats and trawlers. A jog lever provides robust, simple and intuitive steering control, which is particularly suitable in situations where precise maneuvering is critical.
With the GNA 10, the heading can be adjusted directly by pushing the jog lever to the right or left, which provides quick and controlled changes to compass steering. The unit also supports Power Steering mode, where the rudder can be moved manually without active autopilot steering – ideal for harbor maneuvers or slow-speed sailing.
Additionally, the GNA 10 can be connected to an external button and LED indicator, making it easy to switch between compass steering and standby. This provides clear and reliable operation, even under demanding working conditions. Note that jog lever, button and LED light are not included and are not supplied by Garmin.
