Bearing data determines the orientation of the map when the function ‘Orient map > Track up’ is enabled. TwoNav offers you different ways to determine the bearing you are taking during your navigations:
• GPS: The latest positions received are used to calculate the bearing of your current movements. As soon as you stop, this reference will not be reliable because there will be no reliable movements to calculate the bearing.
• Compass: Data recorded from the compass will be used in order to determine the orientation of the device.
• Automatic (recommended):
• Driving slowly: Data recorded from the compass will be used.
• Driving fast: Data recorded from the GPS position will be used.
