DIST (distance to destination): Calculations

The SID unit calculates the ration between DIST, ARRIV and SPD. To carry out these calculations, the value in DIST must be greater than 0.

If an arrival time is then programmed into ARRIV the SID unit will show the calculated average speed, or if a desired average speed is programmed in SPD, the SID unit will show the estimated arrival time in ARRIV.

If the calculation is made when the car is running, the calculated value is replaced by the correct figure after 10 seconds. If the calculation is made with the car stationary, the calculated value is replaced by the correct figure as soon as the car is driven.
