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.‍
5
Symbol Description
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.‍
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

Setting the Safe-Zone Collision Alarm
Before you can set a safe-zone collision alarm, you must have a
compatible chartplotter connected to an AIS device.‍
The safe-zone collision alarm is used only with AIS.‍ The safe
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.‍
2 Select Range.‍
3 Select a distance for the safe-zone radius around your
vessel.‍
4 Select Time To.‍
5 Select a time at which the alarm will sound if a target is
determined to intersect the safe zone.‍
For example, to be notified of a pending intersection 10
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.‍

Courses
CAUTION
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.‍
9
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.‍
NOTE: Auto Guidance is available with premium charts, in
some areas.‍
CAUTION
Garmin recommends using Guide To only under motor power.‍
Using Guide To while under sail can cause an unexpected
gybe, risking damage to the sailboat.‍ Unattended sails and
rigging can be damaged or cause injury to any crew or
passengers during an unexpected gybe maneuver.‍
You can set and follow a course to a destination using one of
three methods: Go To, Route To, or Guide To.‍
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 that avoid land and other obstacles.‍
Guide To: Creates a path to a destination using Auto Guidance.‍
This option is available only when using a compatible
premium chart in a compatible chartplotter.‍ It provides a turnby-turn navigation line to the destination, avoiding land and
other obstacles.‍ The navigation line is based on the chart
data and the safe depth, safe height, and shoreline distance
user-defined chartplotter settings.‍ Using these settings and
chart data, the chartplotter creates a navigation line that
avoids all areas that cannot be navigated between the
present location and the destination.‍ When you are using a
compatible Garmin autopilot connected to the chartplotter
using NMEA 2000®, the autopilot follows the Auto Guidance
route.‍
Setting and Following a Direct Course Using Go To
CAUTION
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.‍
You can set and follow a direct course from your current
location to a selected destination.‍
1 Select a destination (Destinations).‍
2 Select Navigate To > Go To.‍
A magenta line appears.‍ In the center of the magenta line is

off course.‍
3 Follow the magenta line, steering to avoid land, shallow
water, and other obstacles.‍
4 If you are off course, follow the purple line (corrected course)
to go to your destination, or steer back to the magenta line
(direct course).‍
Setting and Following a Course Using Auto Guidance
CAUTION
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,

used as a fishfinder.‍ There are different sonar views to help you
view the fish in the area.‍
The adjustments you can make to each sonar view vary
depending on the view you are in and the chartplotter model,
sounder module, 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

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, a compatible sounder module, 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.‍
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.‍

Sonar Sharing
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.‍
14
This feature may not be available on all chartplotter models.‍
You can view the sonar data from other chartplotters with builtin sonar module connected on the Garmin Marine Network.‍
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 the GPSMAP 741 mounted at
the back of the boat, you can view the sonar data from an
echoMAP 70dv mounted at the front of your boat.‍
Chartplotters can only display sonar types they are compatible
with.‍ For example, the echoMAP 50dv and GPSMAP 547 can
display traditional and DownVü data, but not SideVü data.‍
When sharing sonar data, the values of some sonar settings,
such as Range and Gain are synchronized across the devices
Sonar
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 DownVü 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.‍
Selecting a Sonar Source
This feature may not be available with all models.‍
When you are using more than one sonar data source for a
particular sonar view, you can select the source to use for that
sonar view.‍ For example, if you have two sources for DownVü,
you can select the source to use from the DownVü sonar view.‍
1 Open the sonar view for which you will change the source.‍
2 Select Menu > Sonar Setup > Source.‍
3 Select the source for this sonar view.‍
Renaming a Sonar Source
You can rename a sonar source to easily identify that source.‍
For example, you use "Bow" as the name of the transducer on
the bow of your boat.‍
The source is renamed for the present view only.‍ For example,
to rename the DownVü sonar source, you must open the
DownVü sonar view.‍
1 From the sonar view, select Menu > Sonar Setup > Source
> Rename Sonar Source.‍
2 Enter the name.‍
Customizing the Overlay Numbers

by adjusting the brightness for DownVü and SideVü/DownVü
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 information on the screen.‍ This also increases noise, and
can make it more difficult to recognize actual returns.‍
1 From a sonar view, select Menu.‍
2 Select Gain or Brightness.‍
3 Select an option:
• To increase or decrease the gain or brightness manually,
select Up or Down.‍
• To allow the chartplotter to adjust the gain or brightness

Sonar
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 DownVü and SideVü/
DownVü 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

Adjusting the Range of the Depth or Width
Scale
You can adjust the range of the depth scale traditional and
DownVü sonar views and the range of the width scale for the
SideVü sonar view.‍
Allowing the device to adjust the range automatically keeps the
bottom within the lower or outer third of the sonar screen, and
can be useful for tracking a bottom that has minimal or
moderate terrain changes.‍
Manually adjusting the range enables you to view a specified
range, which can be useful for tracking a bottom that has large
terrain changes, such as a drop-offs or cliffs.‍ The bottom can
appear on the screen as long as it appears within the range you
have set.‍

Setting the Scroll Speed
Creating a Frequency Preset
You can set the rate at which the sonar image moves across
the screen.‍ A higher scroll speed shows more detail, especially
while moving or trolling.‍ A lower scroll speed displays sonar
information on the screen longer.‍ Setting the scroll speed on
one sonar view applies to all the sonar views.‍
1 From a sonar view, select Menu > Sonar Setup > Scroll
Speed.‍
2 Select an option:
• To adjust the scroll speed automatically using speedover-ground or water speed data, select Auto.‍
The Auto setting selects a scroll rate to match the boat
speed, so targets in the water are drawn with the correct
aspect ratio and appear less distorted.‍ When viewing
DownVü or SideVü sonar views, it is recommend to use
the Auto setting.‍
• To use a very fast scroll speed, select Ultrascroll®.‍
The Ultrascroll option quickly scrolls new sonar data, but
with a reduced image quality.‍ For most situations, the
Fast option provides a good balance between a quickly
scrolling image and targets that are less distorted.‍
NOTE: Not available with all transducers.‍
You can create a preset to save a specific sonar frequency,
which allows you to change frequencies quickly.‍
1 From a sonar view, select Menu > Frequency.‍
2 Select Add.‍
3 Enter a frequency.‍
Sonar Frequencies
NOTE: The frequencies available depend on the chartplotter,
sounder modules, and 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 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.‍
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 Frequencies
NOTE: You cannot adjust the frequency for all sonar views and
transducers.‍
You can indicate which frequencies appear on the sonar
screen.‍
1 From a sonar view, select Menu > Frequency.‍
2 Select a frequency suited to your needs and water depth.‍

Radar
WARNING
The marine radar transmits microwave energy that has the
potential to be harmful to humans and animals.‍ Before
beginning radar transmission, verify that the area around the
radar is clear.‍ The radar transmits a beam approximately 12°
above and below a line extending horizontally from the center of
the radar.‍ Avoid looking directly at the radar, because the eyes
are the most susceptible parts of the body.‍
NOTE: Not all models support radar.‍
When you connect your compatible chartplotter to an optional
Garmin marine radar, such as a GMR™ 1206 xHD or a GMR 24
HD, you can view more information about your surroundings.‍
The GMR transmits a narrow beam of microwave energy as it
rotates to a 360° pattern.‍ When the transmitted energy contacts
a target, some of that energy is reflected back to the radar.‍

Select Radar, and select a mode.‍
Cruising Mode: Shows a full-screen image of the gathered
radar information.‍
Harbor Mode: Intended for use in inland waters, this mode
works best with short-range signals (2 nm or less).‍
Offshore Mode: Intended for use in open waters, this mode
works best with long-range signals.‍
Sentry Mode: Allows you to put the radar into timed-transmit
mode, in which you can configure a radar transmit and
standby cycle to conserve power.‍ You can also enable a
guard zone in this mode, which identifies a safe zone around
your boat.‍ If you switch from Sentry mode to another mode,
the radar switches to full-time transmission and disables all
guard zones.‍
Radar Overlay Mode: Shows a full-screen image of the
gathered radar information on top of the Navigation chart.‍
The Radar overlay displays data based on the most recently
used radar mode.‍
Transmitting Radar Signals
NOTE: As a safety feature, the radar enters standby mode after
it warms up.‍ This gives you an opportunity to verify the area
around the radar is clear before beginning radar transmission.‍
1 With the chartplotter off, connect your radar as described in
the radar installation instructions.‍
Turn on the chartplotter.‍
2
The radar warms up and a countdown alerts you when the
radar is ready.‍
3 Select Radar.‍
4 Select a radar mode.‍
A countdown message appears while the radar is starting up.‍
5 Select Menu > Transmit Radar.‍
Range of Radar Signals
The range of the radar signal indicates the length of the pulsed
signal transmitted and received by the radar.‍ As the range
increases, the radar transmits longer pulses in order to reach
distant targets.‍ Closer targets, especially rain and waves, also
reflect the longer pulses, which can add noise to the Radar
screen.‍ Viewing information about longer-range targets can also
decrease the amount of space available on the Radar screen
for viewing information about shorter-range targets.‍
Tips for Selecting a Radar Range
• Determine what information you need to see on the Radar
screen.‍
For example, do you need information about nearby weather
conditions or targets and traffic, or are you more concerned
about distant weather conditions?
• Assess the environmental conditions where the radar is
being used.‍
Especially in inclement weather, longer-range radar signals
can increase the clutter on the Radar screen and make it
more difficult to view information about shorter-range targets.‍
In rain, shorter-range radar signals can enable you to view
information about nearby objects more effectively, if the rain
clutter setting is configured optimally.‍
• Select the shortest effective range, given your reason for
using radar and the present environmental conditions.‍
18
Adjusting the Zoom Scale on the Radar
Screen
The radar zoom scale, also called the radar signal range,

Radar Overlay
When you connect your chartplotter to an optional Garmin
marine radar, you can use the Radar overlay to overlay radar
information on the Navigation chart or on the Fishing chart.‍
The Radar overlay superimposes radar information on the
Navigation chart or the Fishing chart.‍ Data appears on the
Radar overlay based on the most recently used radar mode
(such as Harbor, Offshore, or Sentry), and all settings
configurations applied to the Radar overlay are also applied to
the last-used radar mode.‍ For example, if you use Harbor mode
and then you switch to the Radar overlay, the Radar overlay
would show Harbor mode radar data.‍ If you changed the gain
setting using the Radar overlay menu, the gain setting for
Harbor mode would change automatically.‍
Radar Overlay and Chart Data Alignment
When using the Radar overlay, the chartplotter aligns radar data
with chart data based on the boat heading, which is based by
default on data from a magnetic heading sensor connected
using a NMEA® 0183 or NMEA 2000 network.‍ If a heading
sensor is not available, the boat heading is based on GPS
tracking data.‍
GPS tracking data indicates the direction in which the boat is
moving, not the direction in which the boat is pointing.‍ If the
boat is drifting backward or sideways due to a current or wind,
the Radar overlay may not perfectly align with the chart data.‍
This situation should be avoided by using boat-heading data
from an electronic compass.‍
If the boat heading is based on data from a magnetic heading
sensor or an automatic pilot, the heading data could be
compromised due to incorrect setup, mechanical malfunction,
magnetic interference, or other factors.‍ If the heading data is
compromised, the Radar overlay may not align perfectly with
the chart data.‍

Cleaning the Screen
NOTICE
Cleaners containing ammonia will harm the anti-reflective
coating.‍
The device is coated with a special anti-reflective coating which
is very sensitive to skin oils, waxes, and abrasive cleaners.‍
1 Apply an eyeglass lens cleaner specified as safe for antireflective coatings to the cloth.‍
2 Gently wipe the screen with a soft, clean, lint-free cloth.‍
Calibrating the Touchscreen
You can calibrate the screen if the screen is not properly
responding to the touches.‍ The chartplotter touchscreen does
not normally require calibration.‍
1 Select Settings > System > Display > Calibrate
Touchscreen.‍
2 Follow the on-screen instructions.‍
Screenshots
You can capture a screenshot of any screen shown on your
chartplotter as a bitmap (.‍bmp) file.‍ You can transfer the
screenshot to your computer.‍
Capturing Screenshots
1 Insert a memory card into the card slot.‍
33
2 Select Settings > System > Display > Screenshot Capture
> On.‍
3 Go to a screen you want to capture.‍
4 Hold Home for at least six seconds.‍
Copying Screenshots to a Computer
1 Remove the memory card from the chartplotter, and insert it
into a card reader that is attached to a computer.‍
2 From Windows® Explorer, open the Garmin\scrn folder on
the memory card.‍
3 Copy a .‍bmp file from the card and paste it to any location on
the computer.‍
Troubleshooting
My device will not acquire GPS signals
If the device is not acquiring satellite signals, there could be 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).‍
• If the device is using an internal GPS antenna, make sure
the device has a clear view of the sky so that the internal
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.‍ If the device is mounted inside a cabin and
cannot be placed in a location where the device can acquire
satellites, use an external GPS antenna.‍
• If the device is using an external GPS antenna, make sure
the antenna is connected to the chartplotter or the NMEA
network.‍
• If the device has more than one GPS antenna source, select
a different source (Selecting the GPS Source).‍
Position format is the way in which the GPS receiver's position
appears on the screen.‍ 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 On the chartplotter, select Settings > Units.‍
3 Select the correct map datum and position format settings.‍
4 Create the waypoint again.‍
The touchscreen is not responding to my touches
If the screen is not properly responding to your touches, you
should calibrate the screen.‍ See Calibrating the Touchscreen.‍
The chartplotter touchscreen does not normally require
calibration.‍

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.‍
