ports.
NMEA 2000 Settings
Select Settings > Communications > NMEA 2000 Setup.
Device List: Displays the devices connected to the network.
Label Devices: Changes the labels for available connected
devices.
Naming Devices and Sensors on the Network
You can name devices and sensors connected to the Garmin
Marine Network and the NMEA 2000 network.
1
Select Settings > Communications.
2
Select Marine Network or NMEA 2000 Setup > Device List.
3
Select a device from the list on the left.
4
Select Change Name.
5
Enter the name, and select Done.
Marine Network
The Marine Network allows you to share data from Garmin
peripheral devices with the chartplotters quickly and easily. You
can connect a chartplotter to the Marine Network to receive data
from and share data with other devices and chartplotters that
are compatible with the Marine Network.
Select Settings > Communications > Marine Network.
Setting Alarms
Navigation Alarms
Select Settings > Alarms > Navigation.
Arrival: Sets an alarm to sound when you are within a specified
distance or time from a turn or a destination.
Anchor Drag: Sets an alarm to sound when you exceed a
specified drift distance while anchored.
Off Course: Sets an alarm to sound when you are off course by
a specified distance.
Setting the Anchor Drag Alarm
You can set an alarm to sound if you have moved more than an
allowable distance. This is very useful when anchoring
overnight.
1
Select Settings > Alarms > Navigation > Anchor Drag.
2
Select Alarm to turn on the alarm.
3
Select Set Radius, and select a distance on the chart.
4
Select Back.
System Alarms
Alarm Clock: Sets an alarm clock.
Unit Voltage: Sets an alarm to sound when the battery reaches
a specified low voltage.
GPS Accuracy: Sets an alarm to sound when the GPS location
accuracy falls outside the user-defined value.
Sonar Alarms
NOTE: Not all options are available on all transducers.
From an applicable sonar view, select Menu > Sonar Setup >
Alarms.
You can also open the sonar alarms by selecting 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.
Contour: Sets an alarm to sound when the transducer detects a
suspended target within the specified depth from the surface
of the water and from the bottom.
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.
Setting Weather Alarms
Before you can set weather alarms, you must have a compatible
chartplotter connected to a weather device, such as a GXM
device, and have a valid weather subscription.
1
Select Settings > Alarms > Weather.
2
Turn on alarms for specific weather events.
Setting the Fuel Alarm
Before you can set a fuel level alarm, a compatible fuel flow
sensor must be connected to the chartplotter.
You can set an alarm to sound when the total amount of
remaining onboard fuel reaches the level you specify.
1
Select Settings > Alarms > Fuel > Set Total Fuel Onboard
> On.
2
Enter the remaining amount of fuel that triggers the alarm,
and select Done.
My Vessel Settings
NOTE: Some settings and options require additional charts or
hardware.
Select Settings > My Vessel.
Depth and Anchoring: Allows you to enter information about
the keel (Setting the Keel Offset, page 20) and the anchor.
Temp. Offset: Allows you to set an offset value to compensate
for the water temperature reading from a NMEA 0183 water-
temperature sensor or a temperature-capable transducer
(Setting the Water Temperature Offset, page 50).
Calibrate Water Speed: Calibrates the speed-sensing
transducer or sensor (Calibrating a Water Speed Device,
page 50).
Fuel Capacity: Sets the combined fuel capacity of all the fuel
tanks on your vessel (Setting the Fuel Capacity of the Vessel,
page 37).
Vessel Type: Enables some chartplotter features based on the
boat type.
CZone™: Sets the digital switching circuits.
