signalk-autopilot-furuno

Signal K Autopilot Provider plugin for the Furuno NavPilot (700/711C) via NMEA 2000.

Status: feedback works; remote command is unverified. This plugin reports the NavPilot's live state to Signal K and can act as a feedback provider. Remote command is disabled by default — see "Remote command" below.

What works

• Mode feedback from PGN 127237 Steering Mode: Main Steering → standby, Heading Control Standalone → auto, Track Control → nav.
• Rudder / heading feedback from PGN 127245 / 127237.
• Route following (nav mode): the NavPilot follows an active route on its own from the standard route PGNs (129285 / 129284 / 129283). To command a GOTO from Signal K, emit those as an active route source — use https://github.com/dirkwa/signalk-to-nmea2000.

Remote command (experimental, off by default)

Remote command of this NavPilot over NMEA 2000 is unverified. The plugin can emit Furuno-proprietary command PGNs (126720 for mode, 130827 for course), but they are unproven and may do nothing, so they are gated behind the experimentalCommands setting and disabled by default. The Simrad PGN 130850 an earlier version used is inert, and the standard PGN 126208 is ignored by the pilot. "Adjust ±N°" is sent as an absolute course (there is no relative-course PGN).

Known Limitations

WIND-Mode

• Furuno FAP-7002 does not support wind mode remote https://www.furuno.it/docs/OPERATOR_MANUAL/OME45120D_TZT9F_12F_16F_19F.pdf
