3D chart view.‍
The location of this symbol indicates the closest point of
approach to a dangerous target, and the numbers near the
symbol indicate the time to the closest point of approach to
that target.‍
NOTE: Vessels being tracked with the Blue Force Tracking
feature are indicated with a blue-green color regardless of their
status.‍
Heading and Projected Course of Activated AIS
Targets
When heading and course over ground information are provided
by an activated AIS target, the heading of the target appears on
a chart as a solid line attached to the AIS target symbol.‍ A
heading line does not appear on a 3D chart view.‍
The projected course of an activated AIS target appears as a
dashed line on a chart or a 3D chart view.‍ The length of the
projected course line is based on the value of the projected
heading setting.‍ If an activated AIS target is not transmitting
speed information, or if the vessel is not moving, a projected
Charts and 3D Chart Views
course line does not appear.‍ Changes in the speed, course over
ground, or rate of turn information transmitted by the vessel can
impact the calculation of the projected course line.‍
When course over ground, heading, and rate of turn information
are provided by an activated AIS target, the projected course of
the target is calculated based on the course over ground and the
rate of turn information.‍ The direction in which the target is
turning, which is also based on the rate of turn information, is
indicated by the direction of the barb at the end of the heading
line.‍ The length of the barb does not change.‍
When course over ground and heading information are provided
by an activated AIS target, but rate of turn information is not
provided, the projected course of the target is calculated based
on the course over ground information.‍
Showing AIS Vessels on a Chart or 3D Chart View
Before you can use AIS, you must connect the chartplotter to an
external AIS device and receive active transponder signals from
other vessels.‍
You can configure how other vessels appear on a chart or on a

minutes before it will likely occur, set Time To to 10, and the
alarm will sound 10 minutes before the vessel intersects the
safe zone.‍
AIS Distress Signals
Self-contained AIS distress signal devices transmit emergency
position reports when activated.‍ The chartplotter can receive
signals from Search and Rescue Transmitters (SART),
Emergency Position Indicating Radio Beacons (EPIRB), and
other man overboard signals.‍ Distress signal transmissions are
different than standard AIS transmissions, so they appear
differently on the chartplotter.‍ Instead of tracking a distress
signal transmission for collision avoidance, you track a distress
signal transmission to locate and assist a vessel or person.‍

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.‍
12
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

Sonar
When properly connected to a compatible transducer, your
chartplotter can be used as a fishfinder.‍ Different sonar views
can help you view the fish in the area.‍
Combinations
The adjustments you can make to each sonar view vary
depending on the view you are in and the chartplotter model and
transducer you have connected.‍
Sonar Views
The sonar views available vary depending on the type of
transducer and optional sounder module connected to the
chartplotter.‍ For example, you can view the Split Frequency
view only if you have a dual-frequency transducer connected.‍
There are four basic styles of sonar views available: a fullscreen view, a split-screen view that combines two or more
views, a split-zoom view, and a split-frequency view that
displays two different frequencies.‍ You can customize the
settings for each view in the screen.‍ For example, if you are
viewing the split-frequency view, you can separately adjust the
gain for each frequency.‍
Full-Screen Sonar View
There are several full-screen views available, depending on the
equipment connected.‍ The full-screen sonar views show a large
image of the sonar readings from a transducer.‍ The range scale
along the right side of the screen shows the depth of detected
objects as the screen scrolls from the right to the left.‍

DownVü Sonar View
NOTE: Not all models support DownVü sonar technology and
transducers.‍
NOTE: To receive DownVü scanning sonar, you need a
compatible chartplotter or fishfinder and a compatible
transducer.‍
DownVü high-frequency sonar provides a clearer picture below
the boat, providing a more detailed representation of structures
the boat is passing over.‍
Traditional transducers emit a conical beam.‍ The DownVü
scanning sonar technology emits a narrow beam, similar to the
shape of the beam in a copying machine.‍ This beam provides a
clearer, picture-like image of what is beneath the boat.‍
SideVü Sonar View
NOTE: Not all models support SideVü sonar and scanning
transducers.‍
NOTE: To receive SideVü scanning sonar, you need a
compatible chartplotter and a compatible transducer.‍
SideVü scanning sonar technology shows you a picture of what
lies to the sides of the boat.‍ You can use this as a search tool to
find structures and fish.‍
Split-Screen Sonar Views
The split-screen sonar views enable you to view different
combinations of sonar data simultaneously.‍ For example, you
can view traditional sonar and DownVü sonar views in one
screen.‍ You can edit the layout of a split-screen sonar view to
resize the window and rearrange the data.‍
The scroll rates of the traditional and DownVü sonar views are
synchronized to make the split-screen views easier to read.‍
Split-Zoom Sonar View
The split-zoom sonar view shows a full-view graph of sonar
readings, and a magnified portion of that graph, on the same
screen.‍
Split-Frequency Sonar View
In the split-frequency sonar view, one side of the screen shows
a full-view graph of high frequency sonar data, and the other
side of the screen shows a full-view graph of lower frequency
sonar data.‍
NOTE: The split-frequency sonar view requires the use of a
dual-frequency transducer.‍
Selecting the Transducer Type
Before you can select the transducer type, you must know what
kind of transducer you have.‍
If you are connecting a transducer that was not included with the
chartplotter, you may need to set the transducer type to make

Sonar Frequencies
NOTE: The frequencies available depend on the transducer
being used.‍
Adjusting the frequency helps adapt the sonar for your particular
goals and the present depth of the water.‍
Higher frequencies use narrow beam widths, and are better for
high-speed operation and rough sea conditions.‍ Bottom
definition and thermocline definition can be better when using a
higher frequency.‍
Lower frequencies use wider beam widths, which cover a larger
area and can let the fisherman see more targets, but could also
generate more surface noise and reduce bottom signal
continuity during rough sea conditions.‍ Wider beam widths
generate larger arches for fish target returns, making them ideal
for locating fish.‍ Wider beam widths also perform better in deep
water, because the lower frequency has better deep water
penetration.‍ They can be used to search for structures such as
brush piles.‍
Selecting Frequencies

Troubleshooting
My device will not acquire GPS signals
If the device is not acquiring satellite signals, there could be a
few causes.‍ If the device has moved a large distance since the
last time it has acquired satellites or has been turned off for
longer than a few weeks or months, the device may not be able
to acquire the satellites correctly.‍
• Ensure the device is using the latest software.‍ If not, update
the device software (Updating the Device Software).‍
My device will not turn on or keeps turning off
Devices erratically turning off or not turning on could indicate an
issue with the power supplied to the device.‍ Check these items
to attempt to troubleshoot the cause of the power issue.‍
• Make sure the power source is generating power.‍
You can check this several ways.‍ For example, you can
check whether other devices powered by the source are
functioning.‍
• Check the fuse in the power cable.‍
The fuse should be located in a holder that is part of the red
wire of the power cable.‍ A 3 Amp fuse is used in this power
cable.‍ Check the fuse to make sure there is still a connection
inside of the fuse.‍ You can test the fuse using a multimeter.‍ If
the fuse is good, the multimeter reads 0 ohms.‍
• Check to make sure the device is receiving is at least 10
volts, but 12 volts is recommended.‍
To check the voltage, measure the female sockets 8 (power)
and 2 (ground) of the power cable for DC voltage.‍ If the
voltage is less than 10 volts, the device will not turn on.‍
• If the device is receiving enough power but does not turn on,
contact Garmin product support at www.garmin.com/‍support.‍
My device is not creating waypoints in the correct
location
You can manually enter a waypoint location to transfer and
share data from one device to the next.‍ If you have manually
entered a waypoint using coordinates, and the location of the
point does not appear where the point should be, the map
datum and position format of the device may not match the map
datum and position format originally used to mark the waypoint.‍
Position format is the way in which the GPS receiver's position
appears on the screen.‍ Commonly displayed as latitude/
21
longitude in degrees and minutes, with options for degrees,
minutes and second, degrees only, or one of several grid
formats.‍
Map datum is a math model which depicts a part of the surface
of the earth.‍ Latitude and longitude lines on a paper map are
referenced to a specific map datum.‍
1 Find out which map datum and position format was used
when the original waypoint was created.‍
If the original waypoint was taken from a map, there should
be a legend on the map that lists the map datum and position
format used to create that map.‍ Most often this is found near
the map key.‍
2 On the chartplotter, select Settings > Units.‍
3 Select the correct map datum and position format settings.‍
4 Create the waypoint again.‍
