The display unit for heading data is not solely determined

by the user. If true heading is wanted but the selected

compass is a magnetic compass, then the magnetic

variation must be available from a position- or navigation

source. The same applies if the user wants to read

magnetic heading but receives true heading from the

compass.

If magnetic variation is required but not available, the

compass decides which unit to display.
