Paper maps point to true north. Compasses, however, point to
magnetic north – a region above the Earth where the Earth's
magnetic fields pull. Because magnetic North and true North are
not at the same location, you must set the declination on your
compass. The angle in between magnetic and true north is your
declination.
The declination value appears on most maps. The location of
magnetic north changes yearly, so the most accurate and up-to-date
declination value can be found from websites such as
www.magnetic-declination.com).
Orienteering maps, however, are drawn in relation to magnetic
north. If you are using an orienteering map, you need to turn the
declination correction off by setting the declination value to 0
degrees.
You can set your declination value from the settings under
Navigation » Declination.
