Overview
The Garmin 010-11418-00 is a 32.8 ft (10 m) cable used to connect a heading sensor into an NMEA 0183 network.
It is meant for installations where the heading sensor is mounted away from the helm and you need a clean, continuous run back to the NMEA 0183 connection point on your electronics. A single cable run also helps keep you out of splice repairs in damp chases, bilges, and under-deck conduits.
This is an NMEA 0183 cable, not an NMEA 2000 drop or backbone lead, so it is worth confirming your sensor and receiving device are both set up for NMEA 0183 data.
Key features
- 32.8 ft (10 m) length for typical helm-to-sensor routing on center consoles, cruisers, and sailboats
- Connects a heading sensor to an NMEA 0183 network for heading data distribution
- Used with compatible Garmin radar systems that accept NMEA 0183 heading input, including GMR 18 HD and HD+, GMR 18 xHD, GMR 24 xHD, and GMR 404 and 406 open array systems
- One-piece cable run helps reduce connection points in high-moisture areas
Compatibility and system integration
On many boats, NMEA 0183 is run as point-to-point wiring rather than a shared backbone, so the connection point matters. Confirm where your NMEA 0183 input is located (for example, at the radar interface or at a multifunction display) and plan the cable run accordingly.
If your boat network is primarily NMEA 2000, this cable will not substitute for an NMEA 2000 drop cable. In that case, verify you have an NMEA 0183 interface at the device that needs the heading data.
Installation and routing
Before pulling the cable, map the route from the sensor location to the receiving device and make sure the 10 m length covers the full path, including service loops at both ends. Support the cable so it cannot chafe on fiberglass edges or hardware, and add protection where it passes through bulkheads or deck penetrations.
Try to keep the run separated from high-current wiring like windlass feeds, starter cables, and inverter lines. When crossing power cabling is unavoidable, cross at a right angle and secure the run so it stays fixed under vibration.
Use on board
This cable is a good fit when you are adding a heading sensor to an existing NMEA 0183 setup, or when you are replacing a damaged cable run and want a straightforward, full-length lead that reaches from a central sensor mounting spot back to the helm electronics.
