The navigation system measures the distance with the speedometer pulses. Since
the speedometer pulses depend on the vehicle manufacturer and the tyre size,
when you buy a new vehicle or replace your tyres, the speedometer pulses are
compared with the distance measured with GPS waves and the distance coefficient
is automatically recalibrated.
You can check on the screen whether or not speedometer pulses are being
counted.
