Creating a Basic NMEA 2000 Network
If your boat does not already have an existing NMEA 2000
network installed, you must create a basic NMEA 2000 network.
to create a basic NMEA 2000 network:
1. Connect the three included T-connectors together, side by
side.
2. Connect the terminators to the ends of the combined
T-connectors.
3. Wire the included NMEA 2000 power cable to a 12 Vdc power
source through a switch. Connect the power cable to the
ignition switch of the boat if possible.
4. Connect the NMEA 2000 power cable to the top of one of the
T-connectors.
5. Route and connect the included NMEA 2000 drop cables
from the GPS 17x and from the GPSMAP 6000/7000 series
chartplotter to the tops of the other T-connectors.
NotES:
• The diagram shows only the NMEA 2000 data connection
to the GPSMAP 6000/7000 series chartplotter. The
chartplotter must also be connected to power or it will not
function (page 7).
• One GPS antenna will provide position data for every
device on the NMEA 2000 network. Do not connect
multiple GPS antennas if you are using multiple
chartplotters.
Wiring a Garmin Marine Network
The optional Garmin Marine Network is a plug-and-play system that allows for high-speed data transfer between multiple Garmin chartplotters
and other network-compatible Garmin devices such as a Garmin sonar unit (GSD 22), or a Garmin radar (GMR™ 18 HD or GMR 1206 xHD).
The GPSMAP 6000/7000 series chartplotters have three network ports that can be used to connect other Garmin network-compatible
chartplotters and devices. If the network requires more ports, use a Garmin Marine Network port extender (GMS 10), or another GPSMAP
6000/7000. Data from each connected component is shared by all the connected Garmin chartplotters.
NoteS:
• NMEA 0183 devices must all be wired to one chartplotter on the network. The data is then shared over the network to other connected
chartplotters.
• Connect all chartplotters to the NMEA 2000 network as well as to the Garmin Marine Network. NMEA 2000 data is not shared over the
Garmin Marine Network.
• Connect network components, such as a Garmin GMR radar or GSD sounder to any chartplotter on the network or to an optional GMS 10
Network Port Expander. Data is shared between all chartplotters on the network.

chartplotter.
• Video inputs from the Marine Video cables are only viewable on the connected chartplotter.
• You can connect a GPSMAP 6000/7000 chartplotter to a Marine Network with a GPSMAP 3000 series chartplotter:
◦ They will share GPS position information as well as information to and from standard NMEA 0183 devices.
◦ They will share information from connected network compatible Garmin devices such as a sonar unit (GSD 22) or a radar (GMR 18 HD
or GMR 1206 xHD).
◦ Garmin GPSMAP 3000 series chartplotters cannot share cartography data with the GPSMAP 6000/7000 series chartplotters.
• All network components must be connected to the power source of the boat according to their installation instructions. The following
diagrams show only the network connections, not power connections..
