Owner's Manual

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
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).
Adjusting the Distance from Shore
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.
1
Dock your vessel or drop the anchor.
2
Select Settings
> Preferences > Navigation > Auto
Guidance > Shoreline Distance > Normal
.
3
Select a destination that you have navigated to previously.
4
Select Navigate To
> Auto Guidance
.
5
Review the placement of the Auto Guidance line, and
determine whether the line safely avoids known obstacles
and the turns enable efficient travel.
6
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
.
7
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.
8
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 > Farthest.
• If the turns in the Auto Guidance line are too wide, select
Settings > Preferences >
Navigation > Auto Guidance
> Shoreline Distance > Nearest
.
9
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.
10
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.
Communications Settings
NMEA 0183 Settings
Select Settings
> Communications > NMEA 0183 Setup
.
Port Types: See Setting the Communication Format for Each
NMEA
0183 Port.
Output Sentences: See Configuring NMEA 0183 Output
Sentences.
Position Precision: Adjusts the number of digits to the right of
the decimal point for transmission of NMEA output.
XTE Precision: Adjusts the number of digits to the right of the
decimal point for NMEA
crosstalk error output.
Waypoint IDs: Sets the device to transmit waypoint names or
numbers via NMEA
0183 while navigating. Using numbers
may resolve compatibility issues with older NMEA 0183
autopilots.
Defaults: Restores the
NMEA 0183 settings to the original
factory defaults.
Diagnostics: Displays NMEA 0183 diagnostic information.

sentences.
Setting the Communication Format for Each NMEA 0183
Port
You can configure the communication format for each internal
NMEA 0183 port when connecting your chartplotter to external
NMEA 0183 devices, a computer, or other Garmin devices.
