“History of Error” stores error occurrences up to 50, and errors after the 51st are displayed as the 50th.
Diagnosis by History of Errors
When having a difficulty on the investigation of cause due to multiple errors with a reproducible malfunction,
turn ON the ignition switch from OFF mode after making a memo of the item and number of time (or delete
“History of Error”). Check “History of Error” again after the malfunction was reproduced, and then perform
diagnosis focusing on the item of which number of time increased.

Location detection accuracy of the navigation
system will deteriorate, depending on the error
area in the memory, because GPS cannot

Correct time may not be displayed.

After the power is turned on, the system
always takes some time until GPS positioning
becomes possible. (The GPS receiver starts
positioning without re-collecting the whole sat-
ellite information when it judged the data
stored in the receiver is correct.)

Display Longitude & Latitude

Adjust the pointer with using the joystick and touch “Set”.

The longitude and latitude are displayed.
Speed Calibration

During normal driving, distance error caused by tire wear and
tire pressure change is automatically adjusted for by the auto-
matic distance correction function. This function, on the other
hand, is for immediate adjustment, in cases such as driving with
tire chain fitted on tires.
Angle Adjustment

Adjusts turning angle output detected by the gyroscope.

Initialize Location
Description

Location data for GPS in the Center control unit is initialized in Europe by this mode. Then it is possible for
Center control unit to receive GPS signals for short time.
How to perform “Initialize Location” mode
1. select “Initialize Location”, and push “ENTER”.
2. A message “Please wait.” is displayed and then backs to
another display of “Confirmation/Adjustment” mode.
NOTE:

To continue GPS initialized operation, operate as follows back to
“Map” screen.
–Push “BACK” button twice.
–Push “MAP” button.

After above operation, GPS indicator changes to green color
within half a minute, unless improper GPS located condition.

This operation should be performed in out side field.
FEATURE RESTRICTION SETTING
Operations of navigation system that are performed while driving
can be restricted by using this function.
CAUTION:
Once operational restrictions are imposed, they can not be can-
celled even when the software is updated or the language-
switching program is loaded.
