Viewing Aerial Photos of Landmarks
Before you can view aerial photos on the Navigation chart, you
must turn on the Photo setting in the chart setup.
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.
NOTE: This feature is available with premium charts, in some
areas.
You can use aerial photographs of landmarks, marinas, and
harbors to help orient yourself to your surroundings or to
acquaint yourself with a marina or a harbor prior to arrival.
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.
Select Review > Aerial Photo.

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.
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.
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.
Showing AIS and MARPA Vessels on a Chart or on a
3D Chart View
Before you can show AIS vessels on a chart, you must have an
external AIS device and active transponder signals from other
vessels. Mini Automatic Radar Plotting Aid (MARPA)
functionality works with radar.

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.
NOTE: When using Auto Guidance, a gray segment within
any part of the magenta line indicates that Auto Guidance
cannot calculate part of the Auto Guidance line. This is due
to the settings for minimum safe water depth and minimum
safe obstacle height.
You can set and follow a course to a destination using one of
three methods: Go To, Route To, or Guide To.
Autopilot Navigation
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.
When you start navigation (Go To, Route To, or Guide To), if
you are connected through a NMEA 2000 network to a
compatible Garmin autopilot, you are prompted to engage the
autopilot.
Recalculating the Auto Guidance Route
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.
When navigating with Auto Guidance, select Menu >
Navigation Options > Recalculate Auto Guidance.
Stopping Navigation
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 turn-
by-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.
While navigating, from the Navigation or Fishing chart, select

Select Menu > Stop Navigation.
When navigating with Auto Guidance, select Menu >

Sonar
When properly connected to an optional Garmin sounder
module and a transducer, your compatible chartplotter can be
used as a fishfinder. There are different sonar views to help you
view the fish in the area.
Setting and Following a Direct Course Using Go To
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.
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.

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 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 adjust the gain for
each of the frequencies separately.

Sonar Sharing
This feature may not be available on all chartplotter models.
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.
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 the GPSMAP 8212 mounted at
the back of the boat, you can view the sonar data from an
echoMAP™ 70dv mounted at the front of your boat.
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.
From a sonar view, select Menu > Sonar Menu.

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.
Allowing the device to adjust the range automatically keeps the
bottom within the lower or outer third of the sonar screen, and

Fast option provides a good balance between a quickly
scrolling image and targets that are less distorted.
Selecting the Transducer Type
Before you can select the transducer type, you must know what
kind of transducer you have.
Sonar Frequencies
NOTE: The frequencies available depend on the chartplotter,
sounder modules, and transducer being used.
If you are connecting a transducer that was not included with
the chartplotter, you may need to set the transducer type to
make the sonar function properly. If the device automatically
detected your transducer, this option does not appear.
Adjusting the frequency helps adapt the sonar for your particular
goals and the present depth of the water.

•
•
•
If you have a 200/77 kHz, dual-beam transducer, select
Dual Beam.
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.
If you have a 200/50 kHz, dual-frequency transducer,
select Dual Frequency.
If you have another type of transducer, select it from the
list.
Sonar Setup
NOTE: Not all options and settings apply to all models, sounder
modules, and transducers.
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.
Sonar Settings

Scroll Speed: Sets the rate at which the sonar scrolls from right
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.
In shallow water, you can select a slower scroll speed to
extend the length of time the information is displayed on
screen. In deeper water, you can select a faster scroll speed.
Automatic scroll speed adjusts the scrolling speed to the
speed the boat is traveling.
Viewing two frequencies concurrently using the split-frequency

fields of weak clutter.
By setting the color limit to the color of the undesired returns,
you can eliminate the display of undesired returns on the
screen.
Transmit: Stops the transducer from transmitting.
Shift: Allows you to set the depth range on which the sonar is
focused. This allows you to zoom in a higher resolution in the
focused depth.
Smoothing: Removes noise that is not part of a normal sonar
return, and adjusts the appearance of returns, such as the
bottom.
When using shift, bottom tracking may not work effectively,
because the sonar looks for data within the depth range of
the focused area, which may not include the bottom. Using
shift also can impact the scroll speed, because data outside
the depth range of the focused area is not processed, which
reduces the time required to receive and display the data.
You can zoom in to the focused area, which enables you to
evaluate target returns more closely at a higher resolution
than just zooming alone.
When smoothing is set to high, more of the low-level noise
remains than when using the interference control, but the
noise is more subdued because of averaging. Smoothing
can remove speckle from the bottom. Smoothing and
interference work well together to eliminate low-level noise.
You can adjust the interference and smoothing settings
incrementally to remove undesirable noise from the display.
Surface Noise: Hides surface noise to help reduce clutter.
Wider beam widths (lower frequencies) can show more
targets, but can generate more surface noise.
Echo Stretch: Adjusts the size of the echoes on the screen to
make it easier to see separate returns on the screen.
TVG: Adjusts the time varying gain, which can reduce noise.
When targets are difficult to see, echo stretch makes the
target returns more pronounced and easier to see on the
screen. If the echo stretch value is too high, the targets blend
together, and if the value is too low, the targets might be
small and difficult to see.
This control is best used for situations when you want to
control and suppress clutter or noise near the water surface.
It also allows for the display of targets near the surface that
are otherwise hidden or masked by surface noise.
You can use echo stretch and filter width together to obtain
the preferable resolution and noise reduction. With echo
stretch and filter width set to low, the display has the highest
resolution, but is the most susceptible to noise. With echo
stretch set to high and filter width set to low, the display has
a lower resolution, but has wider targets. With echo stretch
and filter width set to high, the display has the lowest
resolution, but is the least susceptible to noise. It is not
recommended to set echo stretch to low and filter width to
high.

Adjusting the Radar Range
Radar
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.
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.

Tips for Selecting a Radar Range
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.
•
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?
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.
•
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.

Radar Targeting and MARPA
Radar targeting enables you to identify and track objects.
Select Create Waypoint.
Mini-automatic radar plotting aid (MARPA) is primarily used for
collision avoidance. To use MARPA, you assign a MARPA tag
to a target. The radar system automatically tracks the tagged
object and provides you with information about the object,
including the range, bearing, speed, GPS heading, nearest
approach, and time to nearest approach. MARPA indicates the
status of each tagged object (acquiring, lost, tracking, or
dangerous), and the chartplotter can sound a collision alarm if
the object enters your safe zone.
Sentry Mode
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 and
sounds an alarm when a radar object enters the zone. Sentry
mode works with all Garmin GMR model radars.

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.
From a Radar screen or the Radar overlay, select Menu >
Radar Menu > Other Vessels > Display Setup.

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.

inside of the fuse. You can test the fuse using a multimeter. If
the fuse is good, the multimeter reads 0 ohms.
Select the GRID device.
Cleaning the Screen
NOTICE
•
•
Check to make sure the device is receiving is at least 10
volts, but 12 volts is recommended.
Cleaners containing ammonia will harm the anti-reflective
coating.
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.
The device is coated with a special anti-reflective coating which
is very sensitive to skin oils, waxes, and abrasive cleaners.
If the device is receiving enough power but does not turn on,
Apply an eyeglass lens cleaner specified as safe for anti-
reflective coatings to the cloth.
1
Gently wipe the screen with a soft, clean, lint-free cloth.

My device is not creating waypoints in the correct
location
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.
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.
Capturing Screenshots
Insert a memory card into the card slot.
1
2
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.
Select Settings > Preferences > Screenshot Capture >
On.
Go to a screen you want to capture.
3
4
Hold Home for at least six seconds.
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.
Copying Screenshots to a Computer
Remove the memory card from the chartplotter, and insert it
into a card reader that is attached to a computer.
1
2
3
Find out which map datum and position format was used
when the original waypoint was created.
1
®
From Windows Explorer, open the Garmin\scrn folder on
the memory card.
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.
Copy a .bmp file from the card and paste it to any location on
the computer.
Troubleshooting
On the chartplotter, select Settings > Preferences > Units.
Select the correct map datum and position format settings.
Create the waypoint again.

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.

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
