Making the Final Connections to the GPSMAP 4000/5000 Unit
Once the power cable and the GPS 17 antenna (as well as any optional Garmin Marine Network devices, NMEA 0183 devices, NMEA 2000
connections, or video connections) have been wired to the boat, the cables must be connected to the GPSMAP 4000/5000 series unit.
There are seven connectors on the back of the unit, one for power, three for Garmin Marine Network devices, one for the NMEA 0183 cable,
one for a NMEA 2000 cable, and one for the marine video cable.
To attach the power cable, the NMEA 0183 cable, and the marine video cable, carefully press the cable into the correct port on the back of the
unit until it is firmly seated. Do not force the cable, as this may damage the pins. Once the cable is seated, turn the locking ring clockwise
until it stops.
To attach a Garmin Marine Network cable or a NMEA 2000 Micro-connector cable, carefully press the cable into the correct port on the back of
the unit until it is firmly seated. Do not force the cable, as this may damage the pins. Once the cable is seated, turn the locking ring clockwise
until it is tight. Be careful not to overtighten.
