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.

5
Follow the magenta line, steering to avoid land,

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.
