Installing a Garmin Rudder Feedback Sensor
If you installed a drive unit provided by Garmin, rudder feedback data is provided by the drive unit, and a
separate rudder feedback sensor is not required. If you are connecting the autopilot to a drive unit not sold by
Garmin, you must also install a rudder feedback sensor, such as the GRF 10 (sold separately).
Follow the installation instructions provided with your GRF rudder feedback sensor to connect it to your
rudder control and autopilot system.
