2 Measure the target bearing on the radar. 3 If the bearing deviation is more than +/- 1°, set the front-of- boat offset. Setting the Front-of-Boat Offset Before you can set the front-of-boat offset, you must measure the potential front-of-boat offset. The front-of-boat offset setting configured for use in one radar mode is applied to every other radar mode and to the Radar overlay. 1 From a Radar screen or the Radar overlay, select Menu > Radar Setup > Installation > Front of Boat. 2 Select Up or Down to adjust the offset. Setting a Custom Park Position By default, the antenna is stopped perpendicular to the pedestal when it is not spinning. You can adjust this position. 1 From the radar screen, select Menu > Radar Setup > Installation > Antenna Configuration > Park Position. 2 Use the slider bar to adjust the position of the antenna when stopped, and select Back.

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. 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. Autopilot When the 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. When the chartplotter is connected to a compatible Yamaha® autopilot system, you can control the autopilot from the chartplotter using the Yamaha autopilot screen and overlay bar (Yamaha Autopilot, page 41). For information about compatible Yamaha autopilot systems, contact your Yamaha dealer. Opening the Autopilot Screen Before you can open the autopilot screen, you must have a compatible Garmin autopilot installed and configured. Select OneHelm™, A/V, Gauges > Autopilot.

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. TIP: In choppy conditions at low speeds, increasing the Power Saver percentage reduces rudder activity. Enabling Shadow Drive™ NOTE: The Shadow Drive feature is not available on all autopilot models. From the autopilot screen, select Menu > Autopilot Setup > Shadow Drive > Enabled. 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. 39
