NMEA 0183 Settings

Select Settings > Communications > NMEA 0183 Setup.

Sounder: Enables NMEA 0183 output sentences for the

sounder (if applicable).

Route: Enables NMEA 0183 output sentences for routes.

System: Enables NMEA 0183 output sentences for system

information.

Garmin: Enables NMEA 0183 output sentences for Garmin

proprietary sentences.

Posn Precision: Adjusts the number of digits to the right of the

decimal point for transmission of NMEA output.

Waypoint IDs: Sets the device to transmit waypoint names or

numbers via NMEA 0183 while navigating. Using numbers

may resolve compatibility issues with older NMEA 0183

autopilots.

Diagnostics: Displays NMEA 0183 diagnostic information.

Defaults: Restores the NMEA 0183 settings to the original

factory defaults.

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.

Viewing a List of NMEA 2000 Network Devices

You can view the devices connected to the NMEA 2000

network.

Select Settings > Communications > NMEA 2000 Setup >

Device List.

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.

System Alarms

Alarm Clock: Sets an alarm clock.

Device 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.

Setting the Fuel Alarm

Before you can set a fuel level alarm, a compatible fuel flow

sensor must be connected to the NMEA 2000 network.

You can set an alarm to sound when the total amount of

remaining onboard fuel reaches the level you specify.

Select Settings > Alarms > Fuel > Fuel Alarm > On.

Enter the remaining amount of fuel that triggers the alarm.

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.

Select Settings > Alarms > Weather.

Turn on alarms for specific weather events.

Units Settings

Select Settings > Units.

System Units: Sets the unit format for the device.

Variance: Sets the magnetic declination, the angle between

magnetic north and true north, for your present location.

North Reference: Sets the direction references used in

calculating heading information. True sets geographic north

as the north reference. Grid sets grid north as the north

reference (000º). Magnetic sets the magnetic north as the

north reference.

Position Format: Sets the position format in which a given

location reading appears. Do not change this setting unless

you are using a map or chart that specifies a different

position format.

Map Datum: Sets the coordinate system on which the map is

structured. Do not change this setting unless you are using a

map or chart that specifies a different map datum.

Pressure Ref. Time: Sets the reference time used to calculate

the barometer trend. The trend is indicated in the barometer

field.

Time Format: Sets a 12-hour, 24-hour, or UTC time format.

Time Zone: Sets the time zone, or allows automatic selection

based on GPS location.

Navigation Settings

NOTE: Some settings and options require additional charts or

hardware.

Select Settings > Navigation.

Route Labels: Sets the type of labels shown with route turns on

the map.

Auto Guidance: Sets the parameters the chartplotter uses

when calculating an Auto Guidance path, when you are using

some premium maps.

Turn Transition Activ.: Sets the turn transition to be calculated

based on time or distance.

Turn Transition Time: Sets how many minutes before the turn

that you transition to it as the next leg, when Time is selected

for the Turn Transition Activ. setting. You can raise this value

to help improve the accuracy of the autopilot when navigating

a route or an Auto Guidance path with many frequent turns or

at higher speeds. For straighter routes or slower speeds,

lowering this value can improve autopilot accuracy.

Turn Transition Dist.: Sets how far before the turn that you

transition to it as the next leg, when Distance is selected for

the Turn Transition Activ. setting. You can raise this value to

help improve the accuracy of the autopilot when navigating a

route or an Auto Guidance path with many frequent turns or

at higher speeds. For straighter routes or slower speeds,

lowering this value can improve autopilot accuracy.

Route Start: Selects a starting point for route navigation.

Auto Guidance Path Configurations

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.
