during navigation.

Auto Guidance Path Configurations

The Preferred Depth and Safe Height settings influence how the chartplotter
calculates an Auto Guidance path. If an area has an unknown water depth
or an unknown obstacle height, the Auto Guidance path is not calculated in
that area. If an area at the beginning or the end of an Auto Guidance path is
shallower than the Preferred Depth or lower than the Safe Height settings,
the Auto Guidance path may not be calculated in that area, depending on the
map data. On the chart, the course through those areas appears as a gray
line or a magenta and gray striped line. When your boat enters one of those
areas, a warning message appears.
NOTE: Auto Guidance is available with premium charts, in some areas.
NOTE: Not all settings apply to all maps.
You can set the parameters the chartplotter uses when calculating an Auto
Guidance path.
Preferred Depth: Sets the minimum water depth, based on chart depth data,
that your boat can safely travel over.
NOTE: The minimum water depth for the premium charts (made before
2016) is 3 feet. If you enter a value of less than 3 feet, the charts only use
depths of 3 feet for Auto Guidance path calculations.
Safe Height: Sets the minimum height of a bridge or obstacle, based on chart
data, that your boat can safely travel under.
Shoreline Distance: Sets how close to the shore you want the Auto
Guidance path to be placed. The Auto Guidance path may move if you
change this setting while navigating. The available values for this setting
are relative, not absolute. To ensure that the Auto Guidance line is placed

the appropriate distance from shore, you can assess the placement of the
Auto Guidance path using one or more familiar destinations that require
navigation through a narrow waterway (page 33).

Adjusting the Distance from Shore

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.
NOTE: Auto Guidance is available with premium charts, in some areas.
The Shoreline Distance setting indicates how close to the shore you want the
Auto Guidance line to be placed. The Auto Guidance line may move if you
change this setting while navigating. The available values for the Shoreline
Distance setting are relative, not absolute. To ensure the Auto Guidance line
is placed the appropriate distance from shore, you can assess the placement
of the Auto Guidance line using one or more familiar destinations that require
navigation through a narrow waterway.
1 Dock your vessel or drop the anchor.
2 Select Settings > Navigation > Auto Guidance > Shoreline Distance >
Normal.
3 Select a destination that you have navigated to previously.
4 Select Navigate To > Guide To.
5 Review the placement of the Auto Guidance line, and determine whether
the line safely avoids known obstacles and the turns enable efficient travel.
6 Select an option:
• If the placement of the Auto Guidance line is satisfactory, select MENU
> Stop Navigation, and proceed to step 10.
