Orientation to the Vehicle.

To orientate the iPhone to the vehicle, first stop the car on a flat piece of tarmac such as a car-park etc.

From the main screen touch the Centre button . (Using this option does not perform fundamental calibration of the unit accelerometers, it is simply there to re-orientate the iPhone each time it is moved from its dock or cradle).

TrakPal is ready for use when the red dot is centred in accelerometer indicator.
