About Compass
The built-in compass shows which direction your iPhone is pointing and the geographical 
coordinates of your current location. You can have the compass point to magnetic north or  
true north.
Important:   The accuracy of the compass can be affected by magnetic or environmental 
interference; even the magnets in the iPhone earbuds can cause a deviation. Use the digital 
compass only for basic navigation assistance and don’t rely on it to determine precise location, 
proximity, distance, or direction.
If Location Services is turned off when you open Compass, you may be asked to turn it on. You can 
use Compass without turning on Location Services. See “Location Services
”  on page 160.
