Complete an action:
• If the transducer is connected to the chartplotter or a
sonar module, select Settings > My Vessel > Keel
Offset.
• If the transducer is connected to the NMEA 2000 network,
select Settings > Communications > NMEA 2000 Setup
> Device List, select the transducer, and select Review >
Keel Offset.
3
Select if the transducer is installed at the water line, or
select if the transducer is installed at the bottom of the
keel.
Setting the Water Temperature Offset
The temperature offset compensates for the temperature
reading from a temperature sensor or temperature-capable
transducer.
1
Measure the water temperature using the temperature sensor
or temperature-capable transducer that is connected to the
network.
2
Measure the water temperature using a different temperature
sensor or a thermometer that is known to be accurate.
3
Subtract the water temperature measured in step 1 from the
water temperature measured in step 2.
This value is the temperature offset. Enter this value in step 5
as a positive number if the sensor measures the water
temperature as being colder than it actually is. Enter this
value in step 5 as a negative number if the sensor measures
the water temperature as being warmer than it actually is.
4
Complete an action:
• If the sensor or transducer is connected to the chartplotter
or a sonar module, select Settings > My Vessel > Temp.
Offset.
• If the sensor or transducer is connected to the NMEA
2000 network, select Settings > Communications >
NMEA 2000 Setup > Device List, select the transducer,
and select Review > Temp. Offset.
5
Enter the temperature offset value calculated in step 3.
Calibrating a Water-Speed Device
If you have a speed sensor or a speed-sensing transducer
connected, you can calibrate that speed-sensing device to
improve the accuracy of water-speed data displayed by the
chartplotter.
1
Complete an action:
• If the sensor or transducer is connected to the chartplotter
or a sonar module, select Settings > My Vessel >
Calibrate Water Speed.
Device Configuration
• If the sensor or transducer is connected to the NMEA
2000 network, select Settings > Communications >
NMEA 2000 Setup > Device List, select the transducer,
and select Review > Calibrate Water Speed.
2
Follow the on-screen instructions.
If the boat is not moving fast enough or the speed sensor is
not registering a speed, a message appears.
3 Select OK, and safely increase the boat speed.
4
If the message appears again, stop the boat, and ensure the
speed-sensor wheel is not stuck.
5
If the wheel turns freely, check the cable connections.
6 If you continue to get the message, contact Garmin product
support.
Setting the Fuel Capacity of the Vessel
1
Select Settings > My Vessel > Fuel Capacity.
2 Enter the combined total capacity of the fuel tanks.
Synchronizing the Fuel Data with the Actual Vessel
Fuel
You can synchronize the fuel levels in the chartplotter with the
actual fuel in the vessel when you add fuel to your vessel.
1
Select Gauges > Engine > MENU.
2
Select an option:
• After you have filled up all the fuel tanks on the vessel,
select Fill Up All Tanks. The fuel level is reset to
maximum capacity.
• After you have added less than a full tank of fuel, select
Add Fuel to Boat, and enter the amount added.
• To specify the total fuel in the vessel tanks, select Set
Total Fuel Onboard, and enter the total amount of fuel in
the tanks.
Communications Settings
NOTE: Some settings and options require additional charts or
hardware.
Select Settings > Communications.
Serial Port: Sets the input/output format for the serial port to
use when connecting the chartplotter to external NMEA
devices, computers, or other Garmin devices.
NMEA 0183 Setup: Sets the NMEA 0183 sentences the
chartplotter transmits, how many digits to the right of the
decimal point are transmitted in a NMEA output, and how
waypoints are identified
NMEA 2000 Setup: Allows you to view and label the devices on
the NMEA 2000 network
Marine Network: Allows you to view the devices with which you
are sharing maps, sonar, or radar. Not available on all
chartplotter models.
NOTE: You can only view networked data on a model that
supports that data. For example, you cannot view networked
radar on model that does not support radar.
Wi-Fi Network: Allows you set up the Wi‑Fi network

NMEA 0183
The chartplotters support the NMEA 0183 standard, which is
used to connect various NMEA 0183 devices, such as VHF
radios, NMEA instruments, autopilots, wind sensors, and
heading sensors.
To connect the chartplotter to optional NMEA 0183 devices, see
the chartplotter installation instructions.
The approved NMEA 0183 sentences for the chartplotter are
GPAPB, GPBOD, GPBWC, GPGGA, GPGLL, GPGSA, GPGSV,
