Garmin GNA 10 Jog Lever Adapter for Reactor 40 Autopilots

GNA 10 Jog Lever 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 workboats 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.

The Garmin GNA 10 Jog Lever Adapter is an essential accessory designed for displacement hull powerboats equipped with Garmin Reactor 40 autopilots. This adapter enables you to connect a rugged jog lever control, allowing for intuitive manual heading adjustments by pressing left or right. It also supports a Power Steering mode that moves the rudder without autopilot guidance, providing enhanced control during demanding maneuvers. The adapter's compatibility with various jog levers and optional button and LED configurations offers flexible control options tailored to your boat's setup. The GNA 10 seamlessly interfaces via NMEA 2000, ensuring reliable data transfer and power supply from the NMEA 2000 bus operating between 9V and 32V DC. Its IPX7 water rating guarantees durability in harsh marine environments, making it suitable for the rigors of onboard use.

Designed specifically for displacement hull powerboats, the Garmin GNA 10 is compatible with jog levers such as Kobelt 7170, Jastram JO100/JO300, and Simrad S35, which features built-in button and LED status indicators. It supports standard switch types, including DPST OFF-MOM and SPST, with a maximum current of 5mA and voltage of 12V, enabling easy integration with existing marine control systems. Supported LED lights draw 20mA or less, providing visual status updates without overloading the system. The adapter's compact design and 2.8-meter cable length facilitate flexible installation options.

Note that Garmin does not supply the jog lever, button, or LED light, requiring these components to be purchased separately. The GNA 10 can also interface with Jastram digital steering controls and is powered directly through the NMEA 2000 network, simplifying wiring and reducing clutter. Please be aware this product is not compatible with planning hull boats or sailboats, ensuring optimal performance on suitable vessel types.
