GPSMAP 4000/5000 Series Installation Instructions
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.

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.
