Garmin GHP 20 Marine Autopilot System for Viking Owner's Manual - Page 12

Powerboat Autopilot Operation The autopilot follows the man overboard pattern, and the heading screen shows the direction of the turn ➀. ➀ TIP: To quickly resume a pattern after you make a heading adjustment with the helm or the soft keys (page 3), select the center soft key twice. Cancelling a Steering Pattern While following a steering pattern, perform one of the following actions: • Physically steer the boat at the helm (if your autopilot is equipped with Shadow Drive). • Use the soft keys to manually adjust the heading. • Select STBY. GPS Steering Patterns ‹ caution You are responsible for the safe operation of your boat. Do not begin a GPS pattern until you are certain that the water is clear of obstacles. The autopilot can steer the boat along a route defined by your GPS device, or in preset patterns based on a GPS location (waypoint). To use GPS steering, you must have a compatible GPS device connected to the autopilot using NMEA 2000 or NMEA 0183. For more information on connecting a compatible GPS device, see the autopilot installation instructions. GPS steering patterns are based on a GPS waypoint to which you are actively navigating using your optional GPS device. This waypoint is called the active waypoint. 8 GHC 10 Owner's Manual
