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 pre-
mium 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 calcu-
late a suggested path. You can adjust the
path during navigation.
