Connecting a Wireless Device to the Chartplotter

Before you can connect a wireless device to the chartplotter

wireless network, you must configure the chartplotter wireless

network

(page

24).

You can connect a wireless device to the chartplotter to share

data. For example, you can connect an iOS ® device to the

chartplotter to share BlueChart Mobile data.

From the iOS device, select Settings > Wi-Fi.

Select the wireless network name you entered for the

chartplotter network

(page

Enter the password you entered when you set up the

chartplotter as a wireless 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.

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.

Heading: Sets the direction references used in calculating

heading information. Auto Mag Var (automatic magnetic

variation) sets the magnetic declination for your location

automatically. True sets true north as the heading reference.

Grid sets grid north as the heading reference (000º). User

Mag Var allows you to enter the magnetic variation value

manually.

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 Reference Time: Sets the reference time used to

calculate the barometer trend. The trend is indicated in the

barometer field.

Device Configuration

24).

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 measurements for the Safe Depth,

Safe Height, and Shoreline Distance, when you are using

some premium maps.

Turn Transition Activation: 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 Activation. You can raise

this value to help improve the accuracy of the autopilot when

navigating a route or an Auto Guidance line with many

frequent turns or at higher speeds. For straighter routes or

slower speeds, lowering this value can improve autopilot

accuracy.

Turn Transition Distance: Sets how far before the turn that

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

for the Turn Transition Activation. You can raise this value

to help improve the accuracy of the autopilot when

navigating a route or an Auto Guidance line 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 Line Configurations

The Safe Depth and Safe Height settings influence how the

chartplotter calculates an Auto Guidance line. If an area has an

unknown water depth or an unknown obstacle height, the Auto

Guidance line is not calculated in that area. If an area at the

beginning or the end of an Auto Guidance line is shallower than

the safe water depth or lower than the safe obstacle height, the

Auto Guidance line is not calculated in that area. On the chart,

the course through those areas appears as a gray line. When

your boat enters one of those areas, a warning message

appears.

NOTE: Auto Guidance is available with premium charts, in

some areas.

You can set the parameters the chartplotter uses when

calculating an Auto Guidance line.

Safe Depth: Sets the minimum depth (chart depth datum) the

chartplotter uses when calculating an Auto Guidance line.

Safe Height: Sets the minimum height (chart height datum) of a

bridge that your boat can safely travel under.

Shoreline Distance: Sets how close to the shore you want the

Auto Guidance line to be placed. The Auto Guidance line

may move if you change this setting while navigating. The

available values for this setting are relative, not absolute. To

ensure that the Auto Guidance line is placed the appropriate

distance from shore, you can assess the placement of the

Auto Guidance line using one or more familiar destinations

that require navigation through a narrow waterway

(page

26).
