DESCRIPTION
 Trouble diagnosis function of navigation system has a Self Diagnosis mode by automatic operation and a
Confirmation/Adjustment mode by manual operation.
 Self Diagnosis mode checks for connec tions between the units constituting this system, analyzes each indi-
vidual unit at the same time, and displays the results on the display.
 Confirmation/Adjustment mode displays trouble diagnos is that require an operation and a judgment by a
human (auto-decision cannot be performed by the system), confirmation of preset value, and an error his-
tory.

NOTE:
Locations stored in the Address Book and other memory functions may be lost if the vehicle's battery is disconnected or is disc harged. If
this occurs, service the vehicle's battery as necessary and re-enter the information in the Address Book.
VEHICLE MARKS
No map is displayed on the
screen. The DVD-ROM is not inserted, or it is inserted
upside down.
Insert the DVD-ROM correctly.
A screen other than map screen is displayed. Press the “MAP” button.
The pickup lens of the DVD unit is dirty. The pickup lens can become dirty depending
on the usage of the vehicle. Clean the pickup
lens.
The screen is too dim.
The movement is slow. The temperature in the interior of the vehicle is
low. Wait until the interior of the vehicle has warmed
up.
Some pixels in the display are
darker or brighter than others. This condition is an inherent characteristic of liq-
uid crystal displays.
This is not a malfunction.
Some menu items cannot be se-
lected. Some menu items become unavailable while
the vehicle is driven. Park the vehicle in a safe location, then operate
the navigation system.
Symptom Possible cause Possible solution
Symptom Possible cause Possible solution
Names of roads and locations dif-
fer between plan view and BIRD-
VIEW
™ . This is because the quantity of the displayed in-
formation is reduced so that the screen does not
become difficult to read. There is also a chance
that names of the roads or locations may be dis-
played several times, and the names appearing
on the screen may be different because of a pro-
cessing procedure.
This is not a malfunction.
The vehicle mark is not displayed
in the correct position. The vehicle was transported after the ignition
switch was turned off, for example, by a ferry or
car transporter.
Drive the vehicle for a while on a road where
GPS signals can be received.
The position and direction of the vehicle mark
may be incorrect depending on the driving envi-
ronments and the levels of positioning accuracy
of the navigation system. This is not a malfunction. Drive the vehicle for a
while to automatically correct the position and
direction of the vehicle mark.
When the vehicle is travelling on a
new road, the vehicle mark is lo-
cated on another road nearby. The system automatically places the vehicle
mark on the nearest available road, because the
new road is not stored in the map data.
Updated road information will be included in the
next version of the DVD-ROM.
The screen does not switch to the
night screen even after turning on
the headlights. The daytime screen was set the last time the
headlights were turned on.
Set the screen to the night screen mode using
button when turning on the headlights.
The map does not scroll even
when the vehicle is moving. The current location map screen is not dis-
played.
Press the “MAP” button.
The vehicle mark is not displayed. The current location map screen is not dis-
played. Press the “MAP” button.
The GPS indicator on the screen
remains gray. GPS signals cannot be received depending on
the vehicle location, such as in a parking ga-
rage, on a road that has numerous tall buildings,
etc.
Drive on an open, straight road for a while.
A sufficient amount of GPS satellites is not avail-
able. Please wait for the satellites to move to loca-
tions available for the navigation system.
The location of the vehicle mark is
misaligned from the actual posi-
tion. When using tire chains or replacing the tires,
speed calculations based on the speed sensor
may be incorrect.
Drive the vehicle for a while [at approximately
30 km/h (19 MPH) for about 30 minutes] to au-
tomatically correct the vehicle's mark position.
If this does not correct the vehicle mark posi-
tion, inspect the AV system.
The map data has a mistake or is incomplete
(the vehicle mark position is always misaligned
in the same area). Updated road information will be included in the
next version of the DVD-ROM.
