Clear Coefficient - Alpine NVD-A101 SMART MAP PRO Owner's Manual

Clear coefficient

The navigation system measures the distance with the vehicle's speed pulses. Since the vehicle's speed
pulses depend on the vehicle manufacturer and the tire size, when you buy a new vehicle or replace your
tires, the vehicle's speed pulses are compared with the distance measured with GPS waves and the distance
coefficient is automatically recalibrated. To make the recalibration speed faster, clear the current coefficient.
You can check on the screen whether or not vehicle's speed pulses are being counted.
