Axiom 9 Displays EV-1 Magnetic Heading Incorrectly?

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Dan,

The problem reported appears to be limited to the Data Sources dialog. I have verified, albeit with beta software for the next release, that when the Heading data item is displayed within a Databox or as a data item within one of the Data application's panels, that the value reported is in agreement with the autopilot control head ... irrespective of whether True or Magnetic Bearing Mode have been selected. Please additionally note that the Bearing Mode configuration setting is designed to be automatically repeated system-wide. Accordingly, should the MFD be configured for Magnetic Bearing Mode, then the autopilot control head, i70, etc. will all be configured to report magnetic bearings.

However, the problem reported within the Data Sources feature will be logged to seek correction of this problem within a future LightHouse 3 software update. It should be noted that the overwhelming number of customer will not encounter this issue as very few systems are fitted with more than one source of heading data. In systems having a single source of the data for Depth, Speed Through Water, Heading, GPS, GPS Datum, Wind, and Time & Date, the system will automatically use data from the single source. Use of the Data Sources feature is only required when the system features more than one source of the previously specified data sources and would then only be exercised for the corresponding data type(s) for a second source existed within the system.
