Navigation with a Chartplotter

If your vessel has an autopilot system, a dedicated autopilot
control display must be installed at each steering helm in order
to disable the autopilot system.
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.
NOTE: Mariner's Eye 3D and Fish Eye 3D chart views are
available with premium charts, in some areas.
NOTE: The offshore Fishing chart is 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.
Navigating to a Point on the Chart
1
From the Navigation chart or Fishing chart, select a location.
2
If necessary, select SELECT.
3
Select Navigate To.
4
Select an option:
• To navigate directly to the location, select Go To.
• To create a route to the location, including turns, select
Route To.
CAUTION
• To use Auto Guidance, select Guide To.
5
Review the course indicated by the magenta line.
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.
6
Follow the magenta line, steering to avoid land, shallow
water, and other obstacles.
Creating and Navigating a Route From Your Present
Location
You can create and immediately navigate a route on the
Navigation chart or the Fishing chart. This procedure does not
save the route or the waypoint data.
NOTE: The offshore Fishing chart is available with premium
charts, in some areas.
1
From the Navigation chart or Fishing chart, select a
destination.
2
Select Navigate To > Route To.
3
Select the location of the last turn before the destination.
4
Select Add Turn.
5
If necessary, repeat step 3 and 4 to add additional turns,
working backward from the destination to the present
location of your vessel.
The last turn you add should be the first turn you make,
starting from your present location. It should be the turn
closest to your vessel.
6
If necessary, select MENU.
7
Select Navigate Route.
8
Review the course indicated by the magenta line.
