You can choose to navigate with your compass based on either true
north or magnetic north. Magnetic north, which is what a standard compass points to, can
be influenced by several factors and isn't constant. True north, or geographical north,
is what you would see on a paper map and is constant. If you would prefer to navigate
based on true north (for example, if you are using your compass to follow a map) you
must turn on GPS.
In the compass app, do one of the following:
- To navigate based on true north, at the bottom of the
screen, set the switch to On.
- To navigate based on magnetic north, at the bottom of
the screen, set the switch to Off.
