Navigation with a Chartplotter

 CAUTION

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.
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.

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.
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

: 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.
When you are using a compatible Garmin autopilot 

connected to the chartplotter using NMEA 2000

®

, the 

autopilot follows the Auto Guidance route.

Basic Navigation Questions

Question

Answer

How do I make the chartplotter

Setting 

and Following a Direct Course Using 
Go To

.

How do I make the device 
guide me along a straight line 
(minimizing cross track) to a 
location using the shortest 
distance from the present 
location?

using Route To. See 

Creating and 

Navigating a Route From Your Present 
Location

.

Question

Answer

How do I make the device 
guide me to a location while 
avoiding charted obstacles?
