Overview
The Garmin 010-10923-01 is a 2 m (6.5 ft) NMEA 0183 replacement data cable for compatible GPSMAP 4xxx and 5xxx series chartplotters.
It gives you a 19-conductor connection for sending and receiving NMEA 0183 sentences between the plotter and other onboard electronics that still use NMEA 0183, such as VHF radios with DSC, AIS devices, and legacy instrument or autopilot systems.
This is a signal cable, not an NMEA 2000 backbone or drop cable, so it is meant for point-to-point wiring and clean splices behind the helm.
Key features
- 2 m (6.5 ft) overall length for installations where the NMEA 0183 junction is close to the display
- NMEA 0183 interface for sharing navigation and system data with compatible talker and listener devices
- 19-conductor replacement cable used on GPSMAP 4xxx and 5xxx series installations
- Black outer jacket that routes cleanly through dash and console rigging channels
- Useful when replacing a damaged cable or when you need dedicated NMEA 0183 leads without cutting into existing boat wiring
Compatibility and fit
Fits GPSMAP 4xxx and 5xxx chartplotters that use this NMEA 0183 replacement cable connection, including GPSMAP 4008, 4012, 4208, and 4212. Before ordering, confirm your specific model and that the connector and locking collar style at the back of the unit matches your display.
Installation and wiring notes
Plan the run so the cable can reach your splice point without being pulled tight. Leave a little service loop behind the display and support the cable so engine vibration and wave shock are not carried by the connector.
Make NMEA 0183 splices in a dry spot behind the dash or inside a console, then seal them with adhesive-lined heat-shrink butt connectors or a covered terminal block. Keep the data cable separated from high-current DC lines, inverter feeds, and ignition wiring to reduce electrical noise.
On-board use cases
This cable is a good match for boats that keep a GPSMAP 4xxx or 5xxx display in service and need NMEA 0183 data going to a VHF radio, AIS, or older autopilot and instrument gear. It is also handy as a direct replacement when the original NMEA 0183 lead was cut short during a refit.
Maintenance and troubleshooting
If you lose sentences or see intermittent data, start by checking strain on the connector, corrosion at any splices, and shared ground connections between devices. Re-terminate any joints that look green, wet, or loose, and secure the cable so it cannot move and chafe on sharp fiberglass edges.
