Review the placement of the Auto Guidance line, and

determine whether the line safely avoids known obstacles

and the turns enable efficient travel.

Select an option:

• If the placement of the Auto Guidance line is satisfactory,

select MENU > Stop Navigation, and proceed to step 10.

• If the Auto Guidance line is too close to known obstacles,

select Settings > Navigation > Auto Guidance >

Shoreline Distance > Far.

• If the turns in the Auto Guidance line are too wide, select

Settings > Navigation > Auto Guidance > Shoreline

Distance > Near.

If you selected Near or Far in step 6, review the placement of

the Auto Guidance line, and determine whether the line

safely avoids known obstacles and the turns enable efficient

travel.

Auto Guidance maintains a wide clearance from obstacles in

open water, even if you set the Shoreline Distance setting to

Near or Nearest. As a result, the chartplotter may not

reposition the Auto Guidance line, unless the destination

selected requires navigation through a narrow waterway.

Select an option:

• If the placement of the Auto Guidance line is satisfactory,

select MENU > Stop Navigation, and proceed to step 10.

• If the Auto Guidance line is too close to known obstacles,

select Settings > Navigation > Auto Guidance >

Shoreline Distance > Farthest.

• If the turns in the Auto Guidance line are too wide, select

Settings > Navigation > Auto Guidance > Shoreline

Distance > Nearest.

If you selected Nearest or Farthest in step 8, review the

placement of the Auto Guidance line, and determine

whether the line safely avoids known obstacles and the turns

enable efficient travel.

Auto Guidance maintains a wide clearance from obstacles in

open water, even if you set the Shoreline Distance setting to

Near or Nearest. As a result, the chartplotter may not

reposition the Auto Guidance line, unless the destination

selected requires navigation through a narrow waterway.

Repeat steps 3 through 9 at least once more, using a

different destination each time, until you are familiar with the

functionality of the Shoreline Distance setting.

Auto Guidance Line Configurations

CAUTION

The Safe Depth and Safe Height settings influence how the

chartplotter calculates an Auto Guidance line. If an area has an

unknown water depth or an unknown obstacle height, the Auto

Guidance line is not calculated in that area. If an area at the

beginning or the end of an Auto Guidance line is shallower than

the safe water depth or lower than the safe obstacle height, the

Auto Guidance line is not calculated in that area. On the chart,

the course through those areas appears as a gray line. When

your boat enters one of those areas, a warning message

appears.

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

areas.

You can set the parameters the chartplotter uses when

calculating an Auto Guidance line.

Safe Depth: Sets the minimum depth (chart depth datum) the

chartplotter uses when calculating an Auto Guidance line.

NOTE: The minimum safe depth for the premium charts is 3

feet. If you enter a Safe Depth value of less than 3 feet, the

charts only use depths of 3 feet for Auto Guidance route

calculations.

Safe Height: Sets the minimum height (chart height datum) of a

bridge that your boat can safely travel under.

Shoreline Distance: Sets how close to the shore you want the

Auto Guidance line to be placed. The Auto Guidance line

may move if you change this setting while navigating. The

available values for this setting are relative, not absolute. To

ensure that the Auto Guidance line is placed the appropriate

distance from shore, you can assess the placement of the

Auto Guidance line using one or more familiar destinations

that require navigation through a narrow waterway (Adjusting

the Distance from Shore).
