Wiring and Cables The GPSMAP 4000/5000 series chartplotter comes with a power cable, a NMEA 2000 drop cable, a 19-pin NMEA 0183 data cable, and a 17-pin Marine Video cable. Optional Garmin Marine Network components use specialized Garmin Network cables. Depending on the installation, it may be necessary to drill holes to route the connector end of these cables. Garmin rubber grommets are provided to cover these holes for a finished look. You may not need the grommets in some installations. The grommets do NOT create a Trim to this line for the Marine Video waterproof seal. Apply a marine sealant around the grommet and cable after installation. cable. Be sure to test the system before installing and sealing the grommets. Purchase additional grommets from your Garmin dealer or directly from Garmin at www.garmin.com. Use this hole (no trim) for the power, NMEA, Marine Network, or GPS 17 cable. Tools • Drill • 1 1/4 in. (31.7 mm) paddle drill bit or hole saw Split • Utility knife • Marine sealant (optional) To install the cable grommet: 1. Mark the location where you want to route the cable (power, NMEA 0183, NMEA 2000 Marine Video, or Marine Network.) 2. Using a 1 1/4 in. (31.7 mm) paddle drill bit or hole saw, drill the installation hole. 3. Refer to the diagram for trimming instructions. Carefully trim the cable hole in the grommet, as needed. 4. Route the cable to the chartplotter, and test the system. 5. Spread the grommet apart at the split and place it around the cable. 6. Firmly push the grommet into the installation hole until it is seated. Apply marine sealant, as needed, to weatherproof the cable. Wiring the Power Cable The GPSMAP 4000/5000 series chartplotter must be connected to the power supply for the boat. Use the 2-pin power cable included, and connect the power (red) and ground (black) wires. Use 14 AWG shielded wiring for extended runs of wire to the power cable. Solder all connections and seal them with heat-shrink tubing. Wiring the GPS 17 Antenna The GPS 17 antenna must be wired to the included 19-pin NMEA 0183 cable as well as to the power supply for the boat. Refer to the diagram below when wiring the GPS 17 to the 19-pin NMEA 0183 cable. Use 22 AWG shielded wiring for extended runs of wire to the NMEA 0183 cable or GPS 17 cable. Solder all connections and seal them with heat-shrink tubing. Note: If you are using more than one Garmin chartplotter over a Garmin Marine Network, do not wire more than one chartplotter to a GPS antenna. The GPS signal is shared between multiple chartplotters connected to a Garmin Marine Network.
