Point the compass to true north or to magnetic north
You can choose to navigate with your compass using 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, turn on the switch.
- To navigate based on magnetic north, at the bottom of the screen, turn off the switch.
