Garmin gpsmap 4008 User Manual

Using the Garmin Marine Network

The Garmin Marine Network allows you to share data from Garmin peripheral devices between 

Garmin chartplotters quickly and easily. You can connect your GPSMAP 4000 series and GPSMAP 

5000 series chartplotters, and previous Garmin Marine Network compatible chartplotter models 

(GPSMAP 3005/3006/3010), to your network to share data. With the Garmin Marine Network, you 

can:

Share GPS data from a GPS 17 antenna that is wired to one chartplotter, with every chartplotter 

connected to the Garmin Marine Network.
Share NMEA 0183 data from devices that are wired to one chartplotter, with every chartplotter 

connected to the Garmin Marine Network.

  NOtE: Both the GPS 17 and any NMEA 0183 devices must be connected to the same chartplotter to 

achieve the best results when sharing data over the Garmin Marine Network.

  NOtE: If you are using a GSD 21 wired to a GPSMAP 3006/3010 chartplotter, data is shared with 

any GPSMAP 4000 series and GPSMAP 5000 series chartplotters connected to your Garmin Marine 

network. All GSD 21 settings must be configured on the GPSMAP 3006/3010. You cannot wire a GSD 

21 to a GPSMAP 4000 series or GPSMAP 5000 series chartplotter.

Share data from Garmin Marine Network devices connected to any chartplotter in the Marine 

Network or to a GMS 10 Marine Network Port Expander, with every other chartplotter connected 

to the Marine Network. These devices include:

GSD 22 digital sounder—provides sonar data when connected to the Garmin Marine 

Network and an appropriate transducer. Sonar data is shared by all chartplotters on the 

network.
GMR 21/41 Radome; GMR 18 Radome; and GMR 404/406 Open Array Radar—provide 

radar data when connected to the Garmin Marine Network. Radar data is shared by all 

chartplotters on the network.

Share BlueChart g2 Vision cartography data from an SD card inserted in one GPSMAP 4000 

or GPSMAP 5000 series chartplotter with every GPSMAP 4000 and GPSMAP 5000 series 

chartplotter connected to the Marine Network.

  NOtE: BlueChart g2 Vision cartography is only compatible with GPSMAP 4000 and GPSMAP 5000 

series chartplotters. Previous Garmin Marine Network-compatible chartplotter models (such as the 

GPSMAP 3010) can be connected to your network, but they cannot share BlueChart g2 Vision data.

Transfer waypoint, route, and track information from one chartplotter connected to the Garmin 

Marine Network to every other chartplotter connected to the network. The data can be cloned 

from one chartplotter to every other connected chartplotter, or the data can be merged and shared 

with every connected GPSMAP 4000 and GPSMAP 5000 series chartplotter.
