L26-DR GNSS - Dead Reckoning Calibration Procedure

Hi, the L26-DR Application Note page 25 mentions the calibration needed with the car to enable the DR, but if a manufacturer produces thousands of cars do they need to calibrate each one of them? or usually is this the responsibility of the owner of the vehicle?

thanks
