Map Datum: Sets the coordinate system on which the map is

structured. Do not change this setting unless you are using a

map or chart that specifies a different map datum.

Time: Sets the time format, time zone, and daylight saving time.

Navigation Settings

NOTE: Some settings and options require additional charts or

hardware.

Select Settings > Preferences > Navigation.

Route Labels: Sets the type of labels shown with route turns on

the map.

Turn Transition: Adjusts how the chartplotter transitions to the

next turn or leg or the route. You can set the transition to be

based on time or distance before the turn. You can increase

the time or distance value to help improve the accuracy of

the autopilot when navigating a route or an Auto Guidance

line with many frequent turns or at higher speeds. For

straighter routes or slower speeds, lowering this value can

improve autopilot accuracy.

Auto Guidance: Sets the measurements for the Safe Depth,

Safe Height, and Shoreline Distance, when you are using

some premium maps.

Route Start: Selects a starting point for route navigation.

Auto Guidance Line Configurations

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.

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

(page

23).

Adjusting the Distance from Shore

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.

The Shoreline Distance setting indicates 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 the Shoreline Distance

setting are relative, not absolute. To ensure 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.

Dock your vessel or drop the anchor.

Select Settings > Preferences > Navigation > Auto

Guidance > Shoreline Distance > Normal.

Select a destination that you have navigated to previously.

Select Navigate To > Guide To.

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 > Navigation Options > Stop Navigation,

and proceed to step 10.

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

select Settings > Preferences > Navigation > Auto

Guidance > Shoreline Distance > Far.

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

Settings > Preferences > 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.
