Navigating to a Point on the Chart

 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.
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: The offshore Fishing chart is available with premium 

charts, in some areas.
NOTE: Auto Guidance is available with premium charts, in some 

areas.
From the Navigation chart or Fishing chart, select a location.
If necessary, select Select.
Select Navigate To.
Select an option:

• To navigate directly to the location, select Go To.
• To create a route to the location, including turns, select 

Route To.

• To use Auto Guidance, select Auto Guidance.

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.

Follow the magenta line, steering to avoid land, shallow 

water, and other obstacles.

Premium Charts

 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: Not all models support all charts.
Optional premium charts, such as BlueChart g2 Vision®, allow

detailed marine charting, premium charts may contain these 

features, which are available in some areas.
Mariner’s Eye 3D: Provides a view from above and behind the 

boat for a three-dimensional navigation aid.

Fish Eye 3D: Provides an underwater, three-dimensional view 

that visually represents the sea floor according to the 

information on the chart.

Fishing Charts: Shows the chart with enhanced bottom 

contours and without navigational data. This chart works well 

for offshore deep-sea fishing.

High Resolution Satellite Imagery: Provides high-resolution 

satellite images for a realistic view of the land and water on 

the Navigation chart (Showing Satellite Imagery on the 

Navigation Chart).

Aerial Photos: Shows marinas and other navigationally 

significant aerial photos to help you visualize your 

surroundings (Viewing Aerial Photos of Landmarks).

Detailed Roads and POI data: Shows detailed road and point 

of interest (POI) data, which includes highly detailed coastal 

roads and POIs such as restaurants, lodging, and local 

attractions.

Auto Guidance: Uses specified safe depth, safe height, and 

chart data to determine the best course to your destination. 

Auto Guidance is available when you navigate to a 

destination using Guide To.

Viewing Tide Station Information

An indicator for a tide station appears on the chart as a vertical 

bar graph with an arrow. A red arrow pointing downward 

indicates a falling tide, and a blue arrow pointing upward 

indicates a rising tide. When you move the cursor over the tide 

station indicator, the height of the tide at the station appears 

above the station indicator.
Current direction indicators appear as arrows on the chart. The 

direction of each arrow indicates the direction of the current at a 

specific location on the chart. The color of the current arrow 

indicates the range of speed for the current at that location. 

When you move the cursor over the current direction indicator, 

the specific current speed at the location appears above the 

direction indicator.
