Step 2

Calibration of the magnetic field sensor. Input to the navigation computer.

This procedure is only possible after STEP 1 has been completed. Step 2 is carried out in one of three different methods:





a) Preferred method GPS. Calibration using the GPS satellite signals.

b) Alternative method-STREET. Calibration using STREET as a DIGITIZED ADDRESS.

c) Alternative method-ANGLE.

Calibration using "ANGLE" means an ANGULAR CALIBRATION using the direction of a long section of road.





Press the button to continue.

a) Preferred method-GPS. Select GPS and press the rotary knob.





After selecting START and pressing the knob, drive the vehicle in different directions until the navigation computer fixes the field sensor inputs. It may require several minutes of driving to complete this step. The roads should be as straight as possible and free from any overhead obstructions that might block the upward view to the satellite signals.





Press the rotary knob to CONTINUE.





b) Alternative method-STREET as a DIGITIZED ADDRESS. This procedure can only be used within a fully digitized CD map area. The actual location is entered into the On Board Monitor and the navigation system will display a route between two road intersections along which the vehicle must be driven.





If the city is not already displayed enter it in the same method as entering a destination. Enter the STREET at which you want to start the calibration. Select the intersection button. Select the street from the list of intersecting streets that is close to where the vehicle is at this point. Select the IN DIRECTION button. This brings up a list of streets that are in the direction of your planned calibration drive. Select the street that is in your planned direction of travel Select return and press the knob. Press START when you begin to drive. The screen will automatically confirm that the calibration was successful. Select CONTINUE and press the knob to go to STEP 3.





c) Alternative method-ANGLE.

Select ANGLE and press the rotary knob.





ANGULAR CALIBRATION uses the direction of a long section of road. To use this method, the geographical angle of the road must be known and input into the navigation computer to within 1 degree1 then the vehicle must be driven along this route. This option is not recommended.
