Garmin Marine Network Cable Coupler, RJ45 Electrical Accessory
The Garmin Marine Network Cable Coupler is an RJ45 electrical accessory weighing 0.37 lbs and measuring 3.5 × 1.5 × 1 in, used to join two Garmin Marine Network cables end-to-end. Marine electronics installers fit this unit to extend the reach of a vessel’s Garmin network bus between chartplotters, radar units, and GPS systems.

Compatibility & Applications
- Joins two Garmin Marine Network RJ45 large-connector cables end-to-end to extend network reach.
- Pairs with Garmin GMR radar, GPSMAP chartplotters, and GDL series devices on the legacy Garmin Marine Network.
- Fits ECHOMAP Plus 72cv, 72sv, 73cv, and 73sv series chartplotter installations.
- Wires into the legacy Garmin Marine Network, which uses standard RJ45 connectors with water-resistant locking collars.
- Mounts inline between two RJ45 cable runs; no soldering or custom crimping required.
In a typical installation, the coupler bridges two Garmin Marine Network cable segments across a cabin bulkhead to connect a GPSMAP chartplotter at the helm to a GMR radar unit mounted above — without cutting or replacing existing cable runs. Unlike generic RJ45 couplers, the unit is built for the legacy Garmin Marine Network protocol, which uses dedicated twisted pairs for both data and power-on functionality.
