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.

Follow the magenta line, steering to avoid land, shallow

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.
