[CA] Axiom Pro Heading Data from Autopilot

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Kevin,

Please click here to view a FAQ addressing when to use the Data Sources feature. The MFD should not be simultaneously interfaced to the third party autopilot via NMEA 0183 and NMEA 2000.
Should this not be the case and should the Heading (not to be confused with COG) Data overlay, Data application cell, or Sidebar data item report --- as its value, then please respond with the version of software which which is presently installed within the Axiom MFD. Please additionally respond with a data capture from a NMEA 2000 analyzer showing the contents of the 127250 Vessel Heading NMEA 2000 PGN present on the system's NMEA 2000 backbone.
