Courses

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.
When using Go To, a direct course and a corrected course may
pass over land or shallow water. Use visual sightings, and steer
to avoid land, shallow water, and other dangerous objects.
NOTE: Auto Guidance is available with premium charts, in some
areas.
Garmin recommends using Guide To only under motor power.
Using Guide To while under sail can cause an unexpected gybe,
risking damage to the sailboat. Unattended sails and rigging can
be damaged or cause injury to any crew or passengers during
an unexpected gybe maneuver.
You can set and follow a course to a destination using one of
three methods: Go To, Route To, or Guide To.
Go To: Takes you directly to the destination. This is the
standard option for navigating to a destination. The
chartplotter creates a straight line course or navigation line to
the destination. The path may run over land and other
obstacles.
Route To: Creates a route from your location to a destination,
allowing you to add turns along the way. This option provides
a straight line course to the destination, but allows you to add
turns into the route that avoid land and other obstacles.
Guide To: Creates a path to a destination using Auto Guidance.
This option is available only when using a compatible
premium chart in a compatible chartplotter. It provides a turn-
by-turn navigation line to the destination, avoiding land and
other obstacles. The navigation line is based on the chart
data and the safe depth, safe height, and shoreline distance
user-defined chartplotter settings. Using these settings and
chart data, the chartplotter creates a navigation line that
avoids all areas that cannot be navigated between the
present location and the destination.

Setting and Following a Direct Course Using Go To

When using Go To, a direct course and a corrected course may
pass over land or shallow water. Use visual sightings, and steer
to avoid land, shallow water, and other dangerous objects.
You can set and follow a direct course from your current location
to a selected destination.
1
Select a destination (Destinations).
2 Select Navigate To > Go To.
A magenta line appears. In the center of the magenta line is
a thinner purple line that represents the corrected course
from your current location to the destination. The corrected
course is dynamic, and it moves with your boat when you are
off course.
3 Follow the magenta line, steering to avoid land, shallow
water, and other obstacles.
4 If you are off course, follow the purple line (corrected course)
to go to your destination, or steer back to the magenta line
(direct course).
