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:
Some chart views are available with premium charts, in
some areas.
To navigate, you must choose a destination, set a course or
create a route, and follow the course or route. You can follow
the course or the route on the Navigation chart, Fishing chart,
Perspective 3D chart view, or Mariner’s Eye 3D chart view.
You can set and follow a course to a destination using one of
three methods: Go To, Route To, or Auto Guidance.
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 to avoid land and other obstacles.
Auto Guidance
: Uses the specified information about your
vessel and chart data to determine the best path to your
destination. This option is available only when using a
compatible premium chart in a compatible chartplotter. It
provides a turn-by-turn navigation path to the destination,
avoiding land and other obstacles (
).
When you are using a compatible Garmin autopilot
connected to the chartplotter using NMEA 2000
®
, the
autopilot follows the Auto Guidance route.
NOTE:
Auto Guidance is available with premium charts, in
some areas.

clearance. Carefully compare the course to all visual sightings,
and avoid any land, shallow water, or other obstacles that may
be in your path.
