3After confirming all the above connections, drive the car to start calibration.

•This process can take five minutes or more depending on the average speed driven.

•A certain speed (greater than 40 km/h) is required for calibration.

•Calibration time differs among the cars.

•During calibrating, you can use the AV functions of the unit (you can listen to the music, etc.)

•If you turn off the ignition switch, calibration is temporarily stopped. When it is turned on, calibration will restart.

Once calibration is finished, the arrowhead icon turns red and the current position information appears instead of Calibrating.... Learning Lv. (maximum level is 4) reaches 1 after calibration finished.

Navigation (functions such as guidance or route simulation) cannot be used until calibration is complete.
