Wiring and Cables

The GPSMAP 4000/5000 series unit comes with a power 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 waterproof seal. Apply a marine sealant around the grommet and cable after installation. 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.

1.Mark the location where you want to route the power, NMEA 0183, Marine Video, or Marine Network cable.

2.Using a 1 1/4" (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 unit, 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 unit must be connected to the boat’s power supply. 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.
