User manual

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 automatic-
steering functions and patterns.
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 42). 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 A/V, Gauges, Controls > Autopilot.

Setting the Power Saver
You can adjust the level of rudder activity.
1

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.
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 >

Adjusting the Heading with the Helm
NOTE: You must enable the Shadow Drive feature before you

With the autopilot engaged, manually steer the boat.
The autopilot activates Shadow Drive mode.
When you release the helm and manually maintain a specific
heading for a few seconds, the autopilot resumes a heading
hold at the new heading.
Adjusting the Heading with the Chartplotter in Step
