Auto Guidance
WARNING
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.
All route and navigation lines displayed on the chartplotter
are only intended to provide general route guidance or to
identify proper channels, and are not intended to be
precisely followed. Always defer to the navaids and
conditions on the water when navigating to avoid
groundings or hazards that could result in vessel damage,
personal injury, or death.
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.
Setting and Following an Auto Guidance Path

Follow the magenta line, steering to avoid land,
shallow water, and other obstacles.
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.

selected point. This allows you to time your arrival at a
location, such as a bridge opening or a race starting line.

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.
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.
