[CA] [CA11] Replacing Fluxgate compass

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Ray,

Unlike later autopilot course computer designs, the Type 100/300 autopilot course computers were not designed to accept heading data from a NMEA 0183 source. While the HDG NMEA 0183 data sentences is listed among the supported input sentences, the Type 100/300 autopilot course computer was only extracting variation from this NMEA 0183 sentence. Accordingly, this course computer must be used with the M81190 Fluxgate Compass.
