As the vehicle moves, the navigation system receives speed pulses from the PCM. These pulses are converted using a conversion factor to a mph speed that moves the vehicle position (VP) on the map. The navigation system has an internal tuning function that generates and refines this factor based on actual driving. The Study indicates the status of the tuning. At navigation initialization, it begins at 0, and increases to 10 as the navigation system is used.
