Auto Guidance
CAUTION
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.
You can use Auto Guidance to plot the best path to your
destination. Auto Guidance uses your chartplotter to scan chart
data, such as water depth and known obstacles, to calculate a
suggested path. You can adjust the path during navigation.

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.

Auto Guidance Path Configurations
CAUTION
The Preferred Depth and Vertical Clearance 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 Vertical
Clearance 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.
