Symptom
Cause
Remedy
Map screen and BIRDVIEW ™
name of the place vary with the
screen.
Some thinning of the character data is done to
prevent the display becoming to complex. In
some cases and in some locations, the display
contents may differ.
The same place name, street name, etc. may not
be displayed every time on account of the data
processing.
System is not malfunction.
Vehicle mark is not positioned cor-
rectly.
Vehicle is transferred by ferry or by towing after its
ignition switch is turned to OFF.
Drive the vehicle for a while in the GPS sat-
ellite signal receiving condition.
Screen will not switch to nighttime
mode after the lighting switch is
turned ON.
The daytime screen is selected by the “SWITCH
SCREENS” when the last time the screen dim-
ming setting is done.
Switching between daytime/nighttime screen may
be inhibited by the automatic illumination adjust-
ment function.
Perform screen dimming and select the
nighttime screen by “SWITCH SCREENS”.
Map screen will not scroll in accor-
dance with the vehicle travel.
Current location is not displayed.
Press “MAP” switch to display the current
location.
Vehicle mark will not be shown.
Current location is not displayed.
Press “MAP” switch to display the current
location.
Accuracy indicator (GPS satellite
mark) on the map screen stays
gray.
GPS satellite signal is intercepted because the
vehicle is in or behind a building.
Move the vehicle out to an open space.
GPS satellite signal cannot be received because
an obstacle is placed on top of the display.
Do not place anything in the center on top of
the display.
GPS satellites are located badly.
Wait until the location becomes better.
Vehicle location accuracy is low.
Accuracy indicator (GPS satellite mark) on the
map screen stays gray.
Current location is not determined.
Vehicle speed setting by the vehicle speed pulse
has been deviated (advanced or retarded) from
the actual vehicle speed because tire chain is fit-
ted or the system has been used on another vehi-
cle.
Drive the vehicle for a while [for approx. 30
minutes at approx. 30 km/h (19MPH)] and
the deviation will be automatically adjusted.
If advancement or retard still occur, perform
the distance adjustment by Confirmation/
Adjustment Mode mode of diagnosis func-
tion.
Map data has error or omission. (Vehicle mark is
always deviated to the same position.)
As a rule, an updated map DVD-ROM will be
released once a year.
