Setting The Power Saver; Selecting The Preferred Heading Source; Enabling The Shadow Drive™ Feature; Engaging The Autopilot - Garmin ECHOMAP ULTRA Series Owner's Manual

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.

Selecting the Preferred Heading Source

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.
Enabling the Shadow Drive
If the Shadow Drive feature is disabled, steering the boat manually will not disengage the autopilot system. You
must use the helm control or connected chartplotter to disengage the autopilot system.
NOTE: The Shadow Drive feature is not available on all autopilot models.
If the Shadow Drive feature has been disabled, you must enable it again before you can steer the boat manually
to disengage the autopilot system.
1 From the autopilot screen, select Menu > Autopilot Setup > Shadow Drive Setup.
2 If Disabled is shown, select Shadow Drive to enable the Shadow Drive feature.
The Shadow Drive feature is enabled. You can repeat these steps to disable the feature again.

Engaging the Autopilot

When you engage the autopilot, the autopilot takes control of the helm and steers the boat to maintain your
heading.
From the Autopilot screen, select Menu > Engage Heading Hold or Menu > Engage Circle.
Your intended heading shows in the center of the Autopilot screen.
