 GPSMAP 700 Series Installation Instructions
Connecting the Chartplotter to a NMEA 2000 Network (optional)
You can connect the GPSMAP 700 series chartplotter to your existing NMEA 2000 network. You will need the appropriate NMEA 2000 cables
and connectors, either to connect the chartplotter to your existing NMEA 2000 network or to build a NMEA 2000 network if you do not have
one installed on your boat. Contact your local Garmin dealer.
If you are unfamiliar with NMEA 2000, read the “NMEA 2000 Network Fundamentals” chapter of the Technical Reference for Garmin NMEA
2000 Products. The document is located on the included CD and on the NMEA 2000 section of the Garmin Web site at http://www.garmin.
com/garmin/cms/us/onthewater/nmea2000 .
Connecting the Chartplotter to a Garmin Marine Radar (optional)
You can connect the GPSMAP 700 series chartplotter to a Garmin marine radar such as a GMR™ 18 HD (not included).
to connect the chartplotter to a Garmin marine radar:
1. Install the radar according to the installation instructions provided with the radar.
2. Route the Garmin marine network cable to the chartplotter, and connect it to the radar port.
NotE: The GPSMAP 700 series chartplotter is compatible with a Garmin marine radar, but it is not compatible with the Garmin marine
network. Do not connect other Garmin marine network devices to the radar port on the GPSMAP 700 series chartplotter.
3. Update the chartplotter software ( page 7 ).
Connecting the Chartplotter to a GA 30 Remote GPS Antenna (optional)
The GPSMAP 700 series chartplotter has an internal GPS receiver, but some installations, such as a flush-mount-installation, may not allow
a view of the sky that the device needs to calculate your GPS position. You can install a GA 30 remote GPS antenna (not included) in an
appropriate location and connect it to the chartplotter to provide GPS information.
to connect the chartplotter to a GA 30 antenna:
1. Install the GA 30 antenna according to the instructions provided with the antenna.
2. Route the GA 30 cable to the chartplotter, and connect it to the external GPS antenna connector.
Connecting the Chartplotter to a transducer
If you have a sonar-cable GPSMAP 700 series chartplotter (indicated by an “s” in the product name), you can connect a Garmin transducer to
use sonar-specific features.
to connect the chartplotter to a transducer:
1. Install the transducer according to the instructions provided with the transducer.
2. Route the transducer cable to the chartplotter and connect it to the power/data cable.
