You'll find a small crosshair nn the center of your view. Just focus your view onto a navigation-point for a few seconds, until the little circular animation finishes.
After starting VR-Mode click on "VR Setup" to choose the display-size of your device. If the setup-option is not visible, just tap on your screen to show it.
Click on "Exit VR" to leave VR-Mode. If the option is not visible, just tap on your screen to show it.
