Example of Symptoms Judged Not Malfunction
BASIC OPERATION
Symptom Cause Remedy
No image is shown. Display brightness adjustment is set fully to
DARK side. Adjust the display brightness.
No guide sound is heard. Audio
guide volume is too low or too high. Volume control is set to OFF, MIN or MAX. Adjust the audio guide volume.
Audio guidance is not available while the
vehicle is driving on a dark pink route.
System is not malfunction.
Screen is too dark. Motion of the
image is too slow. Temperature inside the vehicle is low. Wait until the temperature inside the vehicle
reaches the proper temperature.
Small black or bright spots appear
on the screen. Symptom peculiar to a liquid crystal display. System is not malfunction.
VEHICLE MARK
Symptom Cause Remedy
Map screen and BIRDVIEW TName
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 dis-
played every time on account of the data pro-
cessing.
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
ªSWITCH SCREENSº when the last time the
screen dimming setting is done.
Switching between daytime/nighttime screen
may be inhibited by the automatic illumination
adjustment function.
Perform screen dimming and select the night-
time screen by ªSWITCH SCREENSº.
Map screen will not scroll in accor-
dance with the vehicle travel. Current location is not displayed. Push ªMAPº switch to display the current
location.
Vehicle mark will not be shown. Current location is not displayed. Push ªMAPº 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 ®tted or the system has
been used on another vehicle. Drive the vehicle for a while [for approx. 30
minutes at approx. 30 km/h (19 MPH)] and
the deviation will be automatically adjusted. If
advancement or retard still occur, perform the
distance adjustment by ªCONFIRMATION/
ADJUSTMENTº mode of diagnosis function.
Map data has error or omission. (Vehicle
mark is always deviated to the same posi-
tion.) As a rule, an updated map DVD-ROM will be
released once a year.
