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.

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.

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.

because an obstacle is placed on top of the

the display.

Vehicle location accuracy is low. Accuracy indicator (GPS satellite mark) on
the map screen stays gray.

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.

mark is always deviated to the same posi-
tion.) As a rule, an updated map DVD-ROM will be
released once a year.
