[CA11] autohelm with p-70 head not accepting garmin gwind nmea 2000 data

[relentless]

Yes and no, it used a GMI 20 4" multi function display which I have 3 of, it is sending data to my garmin chart plotter but not my autohelm, but no not a "stand alone" display just for the wind unit.

its a mast unit that goes to a GND 10 black box Nexus/Nmea 2000 networked to the displays

I have spoken with garmin tech support as well, everything is functional on the nmea2000/garmin network, there suggestion was check PGN compatibility on your end, raymarmine network end is showing every device on on the network except the GND10 black box
