Calibration
Before using the Navigation System first time, it is required to calibrate the Navigation System.
• After deleting the calibration data (☞ [46] Reset Calibration) or changing the installation
angle (☞ [46] Installation Angle), calibration is also required.
1
Display the map screen.
2
Display the detail screen and check the
connections.
GPS Antenna
• OK ] Connection is OK. ([5]: number of the GPS
satellites whose signal is detected.)
• NG ] Antenna is disconnected or short-circuited.
Speed Signal
Drive the car for a while.
• If the number increases as you speed up the car,
connection is OK.
Parking Brake
Step on the brake pedal, then disengage and engage the
parking brake repeatedly.
• If Off appears when disengaged and On appears when engaged, connection is OK.
If the result is not good, check the connection.
• You can see detailed information on the items of Sensor Status in Information
]
Connection. (☞ [43])

After 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 25 mi/h (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.
