the destination. The path may run over land and other 

obstacles.

Route To: Creates a route from your location to a destination, 

allowing you to add turns along the way. This option provides 

a straight line course to the destination, but allows you to add 

turns into the route that avoid land and other obstacles.

Auto Guidance: Creates a path to a destination using Auto 

Guidance. This option is available only when using a 

compatible premium chart in a compatible chartplotter. It 

provides a turn-by-turn navigation line to the destination, 

avoiding land and other obstacles. The navigation line is 

based on the chart data and the safe depth, safe height, and 

shoreline distance user-defined chartplotter settings. Using 

these settings and chart data, the chartplotter creates a 

navigation line that avoids all areas that cannot be navigated 

between the present location and the destination. When you 

are using a compatible Garmin autopilot connected to the 

chartplotter using NMEA 2000, the autopilot follows the Auto 

Guidance route.

When using Go To, a direct course and a corrected course may 

pass over land or shallow water. Use visual sightings, and steer 

to avoid land, shallow water, and other dangerous objects.
You can set and follow a direct course from your current location 

to a selected destination.

).

Select Navigate To > Go To.
A magenta line appears. In the center of the magenta line is 

a thinner purple line that represents the corrected course 

from your current location to the destination. The corrected 

course is dynamic, and it moves with your boat when you are 

off course.

Follow the magenta line, steering to avoid land, shallow 

water, and other obstacles.

If you are off course, follow the purple line (corrected course) 

to go to your destination, or steer back to the magenta line 

(direct course).

From the Navigation chart or Fishing chart, select MENU > 

Stop Navigation.

Waypoints are locations you record and store in the device.

The Auto Guidance feature is based on electronic chart 

information. That data does not ensure obstacle and bottom 

clearance. Carefully compare the course to all visual sightings, 

and avoid any land, shallow water, or other obstacles that may 

be in your path.
When using Go To, a direct course and a corrected course may 

pass over land or shallow water. Use visual sightings, and steer 

to avoid land, shallow water, and other dangerous objects.
NOTE: Auto Guidance is available with premium charts, in some 

areas.
Before you can navigate to a waypoint, you must create a 

waypoint.

Review the course indicated by the magenta line.
NOTE: When using Auto Guidance, a gray segment within 

any part of the magenta line indicates that Auto Guidance 

cannot calculate part of the Auto Guidance line. This is due to 

the settings for minimum safe water depth and minimum safe 

obstacle height.

Follow the magenta line, steering to avoid land, shallow 

water, and other obstacles.
