Installing the GPSMAP 6000/7000 Series Chartplotter and the GPS 17x Antenna NMEA 2000 Network Connections The GPSMAP 6000/7000 series chartplotter is packaged with the necessary NMEA 2000 connectors and cable to either connect a GPSMAP 6000/7000 series chartplotter and a GPS 17x antenna to your existing NMEA 2000 network, or to build a basic NMEA 2000 network. For more information on NMEA 2000, visit www.garmin.com. If you are unfamiliar with NMEA 2000, be sure to read the "NMEA 2000 Network Fundamentals" chapter of the Technical Reference for Garmin NMEA 2000 Products on the included CD or click on the "Manuals" hyperlink on the product page for your chartplotter at www. garmin.com. For example, www.garmin.com/products/GPSMAP7212/. Connecting to an Existing NMEA 2000 Network If your boat already has a NMEA 2000 network installed, use the included T-connectors and drop cable to connect a GPSMAP 6000/7000 series chartplotter and a GPS 17x antenna to the existing network. Notice If you have an existing NMEA 2000 network on your boat, it should already be connected to power. Do not connect the included NMEA 2000 power cable to an existing NMEA 2000 network. To connect a GPSMAP 6000/7000 series chartplotter and a GPS 17x to your existing NMEA 2000 network: 1. Identify where you want to connect the GPSMAP 6000/7000 series chartplotter and the GPS 17x to your existing NMEA 2000 backbone. 2. Disconnect one side of a NMEA 2000 T-connector from the backbone nearest to the location where you want to connect the chartplotter. To extend the NMEA 2000 backbone (if necessary), connect an appropriate NMEA 2000 backbone extension cable (not included) to the side of the T-connector you disconnected.

Route an included drop cable to the chartplotter and to the top of the T-connector you added to your NMEA 2000 network. If the included drop cable is not long enough, you can add a drop cable extension up to 13 ft. (4 m). If more cable is needed, add an extension to your NMEA 2000 backbone, based on the NMEA 2000 guidelines. NMEA 2000 device (not included) Drop cables (included) T-connectors (included) 5. Disconnect one side of a NMEA 2000 T-connector from the backbone nearest to the location where you want to connect the GPS 17x antenna. To extend the NMEA 2000 backbone (if needed), connect an appropriate NMEA 2000 backbone extension cable (not included) to the side of the T-connector you disconnected. 6. Connect an included T-connector in the NMEA 2000 backbone (for the GPS 17x antenna).

Route an included drop cable from the GPS 17x antenna to the top of the T-connector you added to your NMEA 2000 network. If the included drop cable is not long enough, you can add a drop cable extension up to 13 ft. (4 m). If more cable is needed, add an extension to your NMEA 2000 backbone, based on the NMEA 2000 guidelines. Notes: • The diagram on page 8 shows only the NMEA 2000 data connection to a GPSMAP 6000/7000 series chartplotter. The chartplotter must also be connected to power or it will not function. • 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. GPSMAP 6000/7000 Series Installation Instructions
