[CA] [CA11] ST60+ Displaying HDG in Magnetic but COG in True

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Kevin,

If an external magnetic variation value is available from SeaTalk or NMEA, this will be used by the ST60+ Graphic Display. While the MFD is capable of supplying the system with magnetic variation, the GPS sensor is not. If an external variation input is not available, use the button to set VARIATION ON (See the Variation subsection of the User Calibration chapter of the ST60+ Graphic Installation and Operation Guide, then use the track and reset buttons to set the correct magnetic variation value. If you do not want to display the variation value, use the button to set VARIATION OFF.
