Automatic Identification System
The Automatic Identification System (AIS) enables you to
identify and track other vessels, and alerts you to area traffic.
When connected to an external AIS device, the chartplotter can
show some AIS information about other vessels that are within
range, that are equipped with a transponder, and that are
actively transmitting AIS information.
The information reported for each vessel includes the Maritime
Mobile Service Identity (MMSI), location, GPS speed, GPS
heading, time that has elapsed since the last position of the
vessel was reported, nearest approach, and time to the nearest
approach.
Some chartplotter models also support Blue Force Tracking.
Vessels being tracked with Blue Force Tracking are indicated on
the chartplotter with a blue-green color.
AIS Targeting Symbols
Symbol Description
AIS vessel. The vessel is reporting AIS information. The
direction in which the triangle is pointing indicates the
direction in which the AIS vessel is moving.
Target is selected.
Target is activated. The target appears larger on the chart. A
green line attached to the target indicates the heading of the
target. The MMSI, speed, and direction of the vessel appear
beneath the target, if the details setting has been set to Show.
If the AIS transmission from the vessel is lost, a message
banner appears.
Target is lost. A green X indicates that the AIS transmission
from the vessel is lost, and the chartplotter displays a
message banner asking whether the vessel should continue
to be tracked. If you discontinue vessel tracking, the lost
target symbol disappears from the chart or the 3D chart view.
Dangerous target in range. The target flashes while an alarm
sounds and a message banner appears. After the alarm has
been acknowledged, a solid red triangle with a red line
attached to it indicates the location and the heading of the
target. If the safe-zone collision alarm has been set to Off, the
target flashes, but the audible alarm does not sound and the
alarm banner does not appear. If the AIS transmission from
the vessel is lost, a message banner appears.
Dangerous target is lost. A red X indicates that the AIS
transmission from the vessel is lost, and the chartplotter
displays a message banner asking whether the vessel should
continue to be tracked. If you discontinue vessel tracking, the
lost dangerous target symbol disappears from the chart or the
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
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.
Charts and 3D Chart Views 7

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.

zone is used for collision avoidance, and can be customized.
1
Select Settings > Alarms > AIS > AIS Alarm > On.
A message banner appears and an alarm sounds when an
AIS-activated vessel enters the safe-zone area around your
boat. The object is also labeled as dangerous on the screen.
When the alarm is off, the message banner and audible
alarm are disabled, but the object is still labeled as
dangerous on the screen.

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 Aids to Navigation
An AIS aid to navigation (ATON) is any kind of navigational aid
that is transmitted over the AIS radio. ATONs are displayed on
the charts and have identifying information, such as position and
type.
There are three main kinds of AIS ATONs. Real ATONs
physically exist and send their identifying and location
information from their actual location. Synthetic ATONs
physically exist, and their identifying and location information is
sent from another location. Virtual ATONs do not actually exist,
and their identifying and location information is sent from
another location.
You can view AIS ATONs on the chart when the chartplotter is
connected to a compatible AIS radio. To show AIS ATONs, from
a chart, select MENU > Layers > Chart > Navaid > ATONs.
You can view more information about an ATON if you select the
ATON on the chart.

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.
Navigating to a Distress Signal Transmission
When you receive a distress signal transmission, a distress
signal alarm appears.
Select Review > Go To to begin navigation to the
transmission.

Supported Maps
To help you have a safe and enjoyable time on the water,
Garmin devices only support official maps produced by Garmin

purchasing. Be extra cautious with online sellers. If you have
purchased an unsupported map, return it to the seller.
Garmin Quickdraw Contours Mapping
WARNING
The Garmin Quickdraw Contours mapping feature allows users
to generate maps. Garmin makes no representations about the
accuracy, reliability, completeness or timeliness of the maps
generated by third parties. Any use or reliance on the maps
generated by third parties is at your own risk.
The Garmin Quickdraw Contours mapping feature allows you to
instantly create maps with contours and depth labels for any
body of water.
When Garmin Quickdraw Contours records data, a colored
circle surrounds the vessel icon. This circle represents the
approximate area of the map that is scanned by each pass.
10 Garmin Quickdraw Contours Mapping

A green circle indicates good depth and GPS position, and a
speed under 16 km/h (10 mph). A yellow circle indicates good
depth and GPS position, and a speed between 16 and 32 km/h
(10 and 20 mph). A red circle indicates poor depth or GPS
position, and a speed above 32 km/h (20 mph).
You can view Garmin Quickdraw Contours in a combination
screen or as a single view on the map.
The amount of saved data depends on the size of your memory
card, your sonar source, and the speed of your boat as you
record data. You can record longer when you use a single-beam
sonar. It is estimated that you might be able to record about
1,500 hours of data onto a 2 GB memory card.
When you record data on a memory card in your chartplotter,
the new data is added to your existing Garmin Quickdraw
Contours map, and is saved on the memory card. When you
insert a new memory card, the existing data does not transfer
onto the new card.

Navigation with a Chartplotter
WARNING
All route and navigation lines displayed on the chartplotter are
only intended to provide general route guidance or to identify
proper channels, and are not intended to be precisely followed.
Always defer to the navaids and conditions on the water when
navigating to avoid groundings or hazards that could result in
vessel damage, personal injury, or death.
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.
CAUTION
If your vessel has an autopilot system, a dedicated autopilot
control display must be installed at each steering helm in order
to disable the autopilot system.
NOTE: Some chart views are available with premium charts, in
some areas.
To navigate, you must choose a destination, set a course or
create a route, and follow the course or route. You can follow
the course or the route on the Navigation chart, Fishing chart,
Perspective 3D chart view, or Mariner’s Eye 3D chart view.
You can set and follow a course to a destination using one of
three methods: Go To, Route To, or Auto Guidance.
Go To: Takes you directly to the destination. This is the
standard option for navigating to a destination. The
chartplotter creates a straight-line course or navigation line to
the destination. The path may run over land and other
obstacles.
Route To: Creates a route from your location to a destination,
allowing you to add turns along the way. This option provides
a straight-line course to the destination, but allows you to add
turns into the route to avoid land and other obstacles.
Auto Guidance: Uses the specified information about your
vessel and chart data to determine the best path to your
destination. This option is available only when using a
compatible premium chart in a compatible chartplotter. It
provides a turn-by-turn navigation path to the destination,
avoiding land and other obstacles (Auto Guidance,
page 15).
When you are using a compatible autopilot connected to the
chartplotter using NMEA 2000, the autopilot follows the Auto
Guidance route.
NOTE: Auto Guidance is available with premium charts, in
some areas.

be in your path.
All route and navigation lines displayed on the chartplotter are
only intended to provide general route guidance or to identify
proper channels, and are not intended to be precisely followed.
Always defer to the navaids and conditions on the water when
navigating to avoid groundings or hazards that could result in
vessel damage, personal injury, or death.
NOTE: Auto Guidance is available with premium charts, in some
areas.
You can use Auto Guidance to plot the best path to your
destination. Auto Guidance uses your chartplotter to scan chart
data, such as water depth and known obstacles, to calculate a
suggested path. You can adjust the path during navigation.

Auto Guidance Path Configurations
CAUTION
The Preferred Depth and Vertical Clearance settings influence
how the chartplotter calculates an Auto Guidance path. If an
area has an unknown water depth or an unknown obstacle
height, the Auto Guidance path is not calculated in that area. If
an area at the beginning or the end of an Auto Guidance path is
shallower than the Preferred Depth or lower than the Vertical
Clearance settings, the Auto Guidance path may not be
calculated in that area, depending on the map data. On the
chart, the course through those areas appears as a gray line or
a magenta and gray striped line. When your boat enters one of
those areas, a warning message appears.
NOTE: Auto Guidance is available with premium charts, in some
areas.
NOTE: Not all settings apply to all maps.
You can set the parameters the chartplotter uses when
calculating an Auto Guidance path.
Preferred Depth: Sets the minimum water depth, based on
chart depth data, that your boat can safely travel over.
NOTE: The minimum water depth for the premium charts
(made before 2016) is 3 feet. If you enter a value of less than
3 feet, the charts only use depths of 3 feet for Auto Guidance
path calculations.
Vertical Clearance: Sets the minimum height of a bridge or
obstacle, based on chart data, that your boat can safely
travel under.
Shoreline Distance: Sets how close to the shore you want the
Auto Guidance path to be placed. The Auto Guidance path
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 path using one or more familiar destinations
that require navigation through a narrow waterway (Adjusting
the Distance from Shore, page 16).
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.

Sailing Features
Setting the Vessel Type
You can select your boat type to configure the chartplotter
settings and to use features customized for your boat type.
1
Select Settings > My Vessel > Vessel Type.
2
Select an option.
Sail Racing
You can use the device to increase the likelihood that your boat
will cross the start line of a race exactly when the race begins.
When you synchronize the race timer with the official race
countdown timer, you are alerted at one-minute intervals as the
race start approaches. When you combine the race timer with
the virtual start line, the device measures your speed, bearing,
and remaining time on the countdown timer. The device uses
this data to indicate whether your boat will cross the start line
before, after, or at the correct time to start the race.
Starting Line Guidance
Sailing start line guidance is a visual representation of the
information you need to cross the start line at the optimal time
and speed.
After you set the starboard and port start line pins, and the
target speed and time, and after you start the race timer, a
predictor line appears. The predictor line extends from your
current location toward the start line and the laylines that extend
from each pin.
The end point and color of the predictor line indicate where the
boat will be when the timer expires, based on your current boat
speed.
When the end point is before the start line, the line is white. This
indicates the boat must increase speed to reach the start line on
time.
When the end point is past the start line, the line is red. This
indicates the boat must reduce speed to avoid a penalty for
reaching the start line before the timer expires.
When the end point is on the start line, the line is white. This
indicates the boat is moving at an optimal speed to reach the
start line when the timer expires.
By default, the start line guidance window and the race timer
window appear in the Sail Racing combination screen.
Setting the Starting Line

and sets the length of the laylines.
Sailing Angle: Allows you to select how the device calculates
laylines. The Actual option calculates the laylines using the
measured wind angle from the wind sensor. The Manual
option calculates the laylines using manually entered
windward and leeward angles.
Windward Angle: Allows you to set a layline based on the
windward sailing angle.
Leeward Angle: Allows you to set a layline based on the
leeward sailing angle.
18 Sailing Features

Tide Correction: Corrects the laylines based on the tide.
Filter Time Constant: Filters the layline data based on the time
interval entered. For a smoother layline that filters out some
of the changes in the boat's heading or true wind angle, enter
a higher number. For laylines that display a higher sensitivity
to changes in the boat's heading or true wind angle, enter a
lower number.
Setting the Keel Offset
You can enter a keel offset to compensate the water depth
reading for the transducer installation location. This allows you
to view the depth of the water below the keel or the true depth of
the water, depending on your needs.
If you want to know the water depth below the keel or the lowest
point of your boat and the transducer is installed at the water
line or anywhere above the end of the keel, measure the
distance from the transducer location to the keel of the boat.
If you want to know the true water depth and the transducer is
installed below the water line, measure the distance from the
bottom of the transducer up to the water line.
NOTE: This option is only available when you have valid depth
data.

Sonar Fishfinder
When properly connected to a compatible transducer, your
chartplotter can be used as a fishfinder.
For more information about which transducer is best for your
needs, go to garmin.com/transducers.
Different sonar views can help you view the fish in the area. The
sonar views available vary depending on the type of transducer
and sounder module connected to the chartplotter. For example,
you can view certain Panoptix sonar screens only if you have a
compatible Panoptix transducer connected.
There are four basic styles of sonar views available: a full-
screen 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.
If you do not see an arrangement of sonar views to suit your
needs, you can create a custom combination screen (Creating a
New Combination Page with the ECHOMAP UHD 70/90,
page 2).

compatible transducer. For information about compatible
transducers, go to garmin.com/transducers.
Garmin ClearVü high-frequency sonar provides a detailed
picture of the fishing environment around the boat in a detailed
representation of structures the boat is passing over.
Traditional transducers emit a conical beam. The Garmin
ClearVü scanning sonar technology emits two narrow beams,
similar to the shape of the beam in a copying machine. These
beams provide a clearer, picture-like image of what is beneath
the boat.
Garmin SideVü
™
Sonar View
Not all models provide built-in Garmin SideVü sonar support. If
your model does not provide built-in SideVü sonar, you need a
compatible sounder module and compatible SideVü transducer.
If your model does provide built-in SideVü sonar, you need a

Calibrating the Compass
Before you can calibrate the compass, the transducer must be
installed on the shaft far enough away from the trolling motor to
avoid magnetic interference, and deployed in the water.
Calibration must be of sufficient quality to enable the internal
compass.
NOTE: To use the compass, you must mount the transducer on
the transom or the trolling motor shaft. The compass may not
work when you mount the transducer on the motor.
NOTE: For best results, you should use a heading sensor such
as the SteadyCast
™
heading sensor. The heading sensor shows
the direction the transducer is pointing relative to the boat.
NOTE: Compass calibration is available only for transducers
with an internal compass, such as the PS21-TR transducer.
You can begin turning your boat before calibrating, but you must
fully rotate your boat 1.5 times during calibration.

Sonar Sharing
You can view the sonar data from all compatible sources on the
Garmin Marine Network. You can view sonar data from a
compatible external sonar module, such as a GCV
™
sonar
module. In addition, you can view the sonar data from other
chartplotters that have a built-in sonar module.
Each chartplotter on the network can display sonar data from
every compatible sonar module and transducer on the network,
no matter where the chartplotters and transducers are mounted
on your boat. For example, from one ECHOMAP UHD 92sv
device mounted at the back of the boat, you can view the sonar
data from another ECHOMAP UHD device and Garmin ClearVü
transducer mounted at the front of your boat.
When sharing sonar data, the values of some sonar settings,
such as Range and Gain, are synchronized across the devices
on the network. The values of other sonar settings, such as the
Appearance settings, are not synchronized and should be
configured on each individual device. In addition, the scroll rates
of the various traditional and Garmin ClearVü sonar views are
synchronized to make the split views more cohesive.
NOTE: Using multiple transducers simultaneously can create
cross talk, which can be removed by adjusting the Interference
sonar setting.
Adjusting the Level of Detail
You can control the level of detail and noise shown on the sonar
screen either by adjusting the gain for traditional transducers or
by adjusting the brightness for Garmin ClearVü transducers.
If you want to see the highest intensity signal returns on the
screen, you can lower the gain or brightness to remove lower
intensity returns and noise. If you want to see all return
information, you can increase the gain or brightness to see more
Sonar Fishfinder 23

information on the screen. This also increases noise, and can
make it more difficult to recognize actual returns.

Adjusting the Color Intensity
You can adjust the intensity of colors and highlight areas of
interest on the sonar screen by adjusting the color gain for
traditional transducers or the contrast for Garmin ClearVü and
SideVü/ClearVü transducers. This setting works best after you
have adjusted the level of detail shown on the screen using the
gain or brightness settings.
If you want to highlight smaller fish targets or create a higher
intensity display of a target, you can increase the color gain or
contrast setting. This causes a loss in the differentiation of the
high intensity returns at the bottom. If you want to reduce the
intensity of the return, you can reduce the color gain or contrast.

Pic. Advance: Allows the sonar picture to advance faster by
drawing more than one column of data on the screen for
each column of sounder data received. This is especially
helpful when you are using the sounder in deep water,
because the sonar signal takes longer to travel to the water
bottom and back to the transducer.
The 1/1 setting draws one column of information on the
screen per sounder return. The 2/1 setting draws two
columns of information on the screen per sounder return, and
so on for the 4/1 and 8/1 settings.
Sonar Alarms
WARNING
The sonar alarms feature is a tool for situational awareness only
and may not prevent grounding in all circumstances. It is the
obligation of the vessel operator to ensure safe operation of the
vessel.
CAUTION
The Beeper setting must be turned on to make alarms audible
(System Settings, page 37). Failure to set audible alarms could
lead to injury or property damage.
NOTE: Not all options are available on all transducers.
Select Settings > Alarms > Sonar.
Shallow Water: Sets an alarm to sound when the depth is less
than the specified value.
Deep Water: Sets an alarm to sound when the depth is greater
than the specified value.
FrontVü Alarm: Sets an alarm to sound when the depth in front
of the vessel is less than the specified value, which can help
you avoid running aground (
Setting the FrontVü Depth Alarm,
page 27). This alarm is available only with Panoptix FrontVü
transducers.
Water Temp.: Sets an alarm to sound when the transducer
reports a temperature that is 2°F (1.1°C) above or below the
specified temperature.
Fish
Fish: Sets an alarm to sound when the device detects a
suspended target.
• sets the alarm to sound when fish of all sizes are
detected.
• sets the alarm to sound only when medium or large
fish are detected.
• sets the alarm to sound only when large fish are
detected.
Advanced Sonar Settings
NOTE: Not all options and settings apply to all models and
transducers.
From a sonar view, select MENU > Sonar Setup > Advanced.
Interference: Adjusts the sensitivity to reduce the effects of
interference from nearby sources of noise.
The lowest interference setting that achieves the desired
improvement should be used to remove interference from the
screen. Correcting installation issues that cause noise is the
best way to eliminate interference.
Surface Noise: Hides surface noise to help reduce clutter.
Wider beam widths (lower frequencies) can show more
targets, but can generate more surface noise.
Color Gain: See Adjusting the Level of Detail, page 23.
TVG: Adjusts the appearance of returns to compensate for
weakened sonar signals in deeper water, and reduces the
appearance of noise near the surface. When the value of this
setting is increased, the colors associated with low-level
noise and fish targets appear more consistent through
various water depths. This setting also reduces the noise
near the surface of the water.
Transducer Installation Settings
NOTE: Not all options and settings apply to all models and
transducers.
From a sonar view, select MENU > Sonar Setup > Installation.
Restore Sonar Defaults: Restores the factory default settings
for the sonar view.
Transducer Type: Allows you to select the type of transducer
that is connected to the device.
Flip Left/Right: Changes the orientation of the SideVü sonar
view when the transducer is installed backward.
Flipped: Sets the orientation of the Panoptix sonar view when
the transducer is installed with the cables pointing toward the
port side of the boat.
Beam Width: Sets the width of the Panoptix transducer beam.
Narrow beam widths allow you to see deeper and farther.
Wider beam widths allow you to see more coverage area.
Use AHRS: Allows the internal attitude heading and reference
system (AHRS) sensors to detect the installation angle of the
Panoptix transducer. When this setting is turned off, it is
assumed the transducer is installed at a 45-degree angle.
Sonar Frequencies
NOTE: The frequencies available depend on the chartplotter,
sounder modules, and transducer being used.
Sonar Fishfinder 25

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 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.
CHIRP frequencies allow you to sweep each pulse through a
range of frequencies, resulting in better target separation in
deep water. CHIRP can be used to distinctly identify targets, like
individual fish in a school, and for deep water applications.
CHIRP generally performs better than single frequency
applications. Because some fish targets may show up better
using a fixed frequency, you should consider your goals and
water conditions when using CHIRP frequencies.
Some sonar black boxes and transducers also provide the ability
to customize preset frequencies for each transducer element,
which enables you to change the frequency quickly using the
presets as the water and your goals change.
Viewing two frequencies concurrently using the split-frequency
view allows you to see deeper with the lower frequency return
and, at the same time, see more detail from the higher
frequency return.
Selecting the Transducer Frequency
NOTE: You cannot adjust the frequency for all sonar views and
transducers.
You can select which frequencies appear on the sonar screen.
NOTICE
Always be aware of local regulations on sonar frequencies. For
example, to protect orca whale pods, you might be prohibited
from using frequencies between 50 to 80 khz with in ½ mile of
an orca whale pod. It is your responsibility to use the device in
compliance with all applicable laws and ordinances.

Calibrating the Compass
Before you can calibrate the compass, the transducer must be
installed on the shaft far enough away from the trolling motor to
avoid magnetic interference, and deployed in the water.
Calibration must be of sufficient quality to enable the internal
compass.
NOTE: To use the compass, you must mount the transducer on
the transom or the trolling motor shaft. The compass may not
work when you mount the transducer on the motor.
28 Sonar Fishfinder

NOTE: For best results, you should use a heading sensor such
as the SteadyCast heading sensor. The heading sensor shows
the direction the transducer is pointing relative to the boat.
NOTE: Compass calibration is available only for transducers
with an internal compass, such as the PS21-TR transducer.
You can begin turning your boat before calibrating, but you must
fully rotate your boat 1.5 times during calibration.

Autopilot
WARNING
You can use the autopilot feature only at a station installed next
to a helm, throttle, and helm control device.
You are responsible for the safe and prudent operation of your
vessel. The autopilot is a tool that enhances your capability to
operate your boat. It does not relieve you of the responsibility of
safely operating your boat. Avoid navigational hazards and
never leave the helm unattended.
Always be prepared to promptly regain manual control of your
boat.
Learn to operate the autopilot on calm and hazard-free open
water.
Use caution when operating the autopilot near hazards in the
water, such as docks, pilings, and other boats.
NOTE: This feature is only available on models with NMEA
2000 network capabilities.
The autopilot system continuously adjusts the steering of your
boat to maintain a constant heading (heading hold). The system
also allows manual steering and several modes of automatic-
steering functions and patterns.
When the compatible chartplotter is connected to a compatible
Garmin autopilot system, you can engage and control the
autopilot from the chartplotter.
For information about compatible Garmin autopilot systems, go
to garmin.com.
Autopilot Configuration
NOTICE
To avoid damage to your boat, the autopilot system should be
installed and configured by a qualified marine installer. Specific
knowledge of marine steering and electrical systems is required
for proper installation and configuration.
The autopilot system must be configured to work properly with
your boat. You can configure the autopilot using a chartplotter
on the same NMEA 2000 network as the autopilot. For
configuration instructions, go to support.garmin.com, and
download the configuration guide for your specific autopilot
model.

Power Saver percentage reduces rudder activity.
Selecting the Preferred Heading Source
NOTICE
For best results, use the autopilot CCU internal compass for the
heading source. Using a third-party GPS compass can cause
the data to be delivered erratically and may result in excessive
delays. The autopilot needs timely information, and therefore
cannot often use third-party GPS compass data for GPS
location or speed. If a third-party GPS compass is used, the
autopilot will likely report loss of navigation data and speed
source periodically.
If you have more than one heading source on the network, you
can select a your preferred source. The source could be a
compatible GPS compass or a magnetic heading sensor.
1
From the autopilot screen, select MENU > Autopilot Setup >

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 Using a
Memory Card, page 44).
• Make sure the device has a clear view of the sky so the
antenna can receive the GPS signal. If it is mounted inside of
a cabin, it should be close to a window so it can receive the
GPS signal.
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. Check that the proper size fuse is
installed. Refer to the label on the cable or the installation
instructions for the exact fuse size needed. 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 ohm.
• Check to make sure the device is receiving at least 12 Vdc.
To check the voltage, measure the female power and ground
sockets of the power cable for DC voltage. If the voltage is
less than 12 Vdc, the device will not turn on.
• If the device is receiving enough power but does not turn on,
contact Garmin product support.
Changing the Fuse in the Power Cable
1
Open the fuse housing
.
44 Appendix

2
Twist and pull the fuse to remove it
.
3
Insert a new 3 A fast-blow fuse.
4
Close the fuse housing.
My sonar does not work
• Ensure the locking ring on sonar cable connector is secured.
• Press , and ensure sonar is enabled.
• Select the correct transducer type (Selecting the Transducer
Type, page 23).
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. This is commonly displayed as latitude/
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
Select Settings > Units.
3
Select the correct map datum and position format settings.
4
Create the waypoint again.
My device does not display the correct time
Time is set by GPS position and time zone setting.
1
Select Settings > Units > Time Zone.
