Autopilot WARNING You can use the autopilot feature only at a station installed next to a helm, throttle, and helm control device. You are responsible for the safe and prudent operation of your vessel. The autopilot is a tool that enhances your capability to operate your boat. It does not relieve you of the responsibility of safely operating your boat. Avoid navigational hazards and never leave the helm unattended. Always be prepared to promptly regain manual control of your boat. Learn to operate the autopilot on calm and hazard-free open water. Use caution when operating the autopilot near hazards in the water, such as docks, pilings, and other boats. NOTE: This feature is only available on models with NMEA 2000 network capabilities. The autopilot system continuously adjusts the steering of your boat to maintain a constant heading (heading hold). The system also allows manual steering and several modes of automaticsteering functions and patterns. When the compatible chartplotter is connected to a compatible Garmin autopilot system, you can engage and control the autopilot from the chartplotter. For information about compatible Garmin autopilot systems, go to garmin.com. Autopilot Screen TIP: In choppy conditions at low speeds, increasing the Power Saver percentage reduces rudder activity. Selecting the Preferred Heading Source NOTICE For best results, use the autopilot CCU internal compass for the heading source. Using a third-party GPS compass can cause the data to be delivered erratically and may result in excessive delays. The autopilot needs timely information, and therefore cannot often use third-party GPS compass data for GPS location or speed. If a third-party GPS compass is used, the autopilot will likely report loss of navigation data and speed source periodically. If you have more than one heading source on the network, you can select a your preferred source. The source could be a compatible GPS compass or a magnetic heading sensor. 1 From the autopilot screen, select MENU > Autopilot Setup > Preferred Sources 2 Select a source. If the selected heading source is unavailable, the autopilot screen does not display any data. Engaging the Autopilot When you engage the autopilot, the autopilot takes control of the helm and steers the boat to maintain your heading. From any screen, select Engage. Your intended heading shows in the center of the Autopilot screen. Steering Patterns WARNING You are responsible for the safe operation of your boat. Do not begin a pattern until you are certain that the water is clear of obstacles. Actual heading Intended heading (heading the autopilot is steering toward) Actual heading (when in standby mode) Intended heading (when engaged) Rudder position indicator (This functionality is available only when a rudder sensor is connected.) Adjusting the Step Steering Increment 1 From the Autopilot screen, select MENU > Autopilot Setup > Step Turn Size. 2 Select an increment. Setting the Power Saver You can adjust the level of rudder activity. 1 From the autopilot screen, select MENU > Autopilot Setup > Power Mode Setup > Power Saver. 2 Select a percentage. Selecting a higher percentage reduces rudder activity and heading performance. The higher the percentage, the more the course deviates before the autopilot corrects it. The autopilot can steer the boat in preset patterns for fishing, and it can also perform other specialty maneuvers such as Uturns and Williamson turns. Following the U-Turn Pattern You can use the u-turn pattern to turn the boat around 180 degrees and maintain the new heading. 1 From the autopilot screen, select MENU > Pattern Steering > U-Turn. 2 Select Engage Port or Engage Starboard. Setting Up and Following the Circles Pattern You can use the circles pattern to steer the boat in a continuous circle, in a specified direction, and at a specified time interval. 1 From the autopilot screen, select MENU > Pattern Steering > Circles. 2 If necessary, select Time, and select a time for the autopilot to steer one complete circle. 3 Select Engage Port or Engage Starboard. Setting Up and Following the Zigzag Pattern You can use the zigzag pattern to steer the boat from port to starboard and back, over a specified time and angle, across your present heading. 1 From the autopilot screen, select MENU > Pattern Steering > Zigzag. 2 If necessary, select Amplitude, and select a degree. 3 If necessary, select Period, and select a length of time. 4 Select Engage Zigzag. 28 Autopilot
