+---- Thread: Setting Units / True and Magnetic bearings (/thread-1286.html)
- GPSNavX - October 24, 2010
The Units used in MacENC or GPSNavX are selected by selecting the "Preferences" menu item and then selecting the "Units" button.
Selection of "True" or "Magnetic" bearings is done on the "View" menu.
Selection of Magnetic Variation is done in the "Preferences". Normally this is left with "manual" not checked so that automatic variation is computed.
