Incoming Distress Calls

If your compatible chartplotter and VHF radio are connected

using NMEA 0183 or NMEA 2000, your chartplotter alerts you

when your VHF radio receives a DSC distress call. If position

information was sent with the distress call, that information is

also available and recorded with the call.

designates a distress call in the DSC list and marks the

position of the vessel on the Navigation chart at the time of the

DSC distress call.

Man-Overboard Distress Calls Initiated from a VHF

Radio

When the chartplotter is connected to a compatible VHF radio

with NMEA 2000, and you initiate a man-overboard DSC

distress call from the radio, the chartplotter shows the man-

overboard screen and prompts you to navigate to the man-

overboard point. If you have a compatible autopilot system

connected to the network, the chartplotter prompts you to start a

Williamson's turn to the man-overboard point.

If you cancel the man-overboard distress call on the radio, the

chartplotter screen prompting you to activate navigation to the

man-overboard location disappears.

Man-Overboard and SOS Distress Calls Initiated from

the Chartplotter

When your chartplotter is connected to a Garmin NMEA 2000

compatible radio and you mark an SOS or man-overboard

location, the radio shows the Distress Call page so you can

quickly initiate a distress call.

For information on placing distress calls from your radio, see the

VHF radio owner's manual. For information about marking an

MOB or SOS location, see

an MOB

Location.

Position Tracking

When you connect the chartplotter to a VHF radio using NMEA

0183, you can track vessels that send position reports.

This feature is also available with NMEA 2000, when the vessel

sends the correct PGN data (PGN 129808; DSC Call

Information).

Every position report call received is logged in the DSC list

(DSC

List).

Viewing Vessel Trails on the Chart

You can view trails for all tracked vessels on some chart views.

By default, a black line indicates the path of the vessel, a black

dot indicates each previously reported position of a tracked

vessel, and a blue flag indicates the last reported position of the

vessel.

From a chart or 3D chart view, select Menu > Other Vessels

> DSC Trails.

Select the number of hours to show tracked vessels on the

chart.

For example, if you select 4 Hours, all trail points that are

less than four hours old appear for all tracked vessels.

Individual Routine Calls

When you connect the chartplotter to a Garmin VHF radio, you

can use the chartplotter interface to set up an individual routine

call.

When setting up an individual routine call from your chartplotter,

you can select the DSC channel on which you want to

communicate. The radio transmits this request with your call.

Selecting a DSC Channel

NOTE: The selection of a DSC channel is limited to those

channels that are available in all frequency bands. The default

channel is 72. If you select a different channel, the chartplotter

uses that channel for subsequent calls until you call using

another channel.

Select Nav Info > Other Vessels > DSC List.

Select a vessel or a station to call.

Select Call with Radio > Channel.

Select an available channel.

Making an Individual Routine Call

NOTE: When initiating a call from the chartplotter, if the radio

does not have an MMSI number programmed, the radio will not

receive call information.
