Location Correction by Map-Matching is Slow
• The map-matching function needs to refer to the data of the surrounding area. It is necessary to drive some
distance for the function to work.
• Because map-matching operates on this principle, when there are many roads running in similar directions
in the surrounding area, no matching determination may be made. The location may not be corrected until
some special feature is found.
Name of Road is Not Displayed
The current road name may not be displayed if there are no road names displayed on the map screen.
Contents of Display Differ for Birdview™ and the (Flat) Map Screen
Difference of the BIRDVIEW™ screen from the flat map screen are as follows.
• The current place name displays names which are primarily in the direction of vehicle travel.
• The amount of time before the vehicle travel or turn angle is updated on the screen is longer than for the
(flat) map display.
• The conditions for display of place names, roads, and other data are different for nearby areas and for more
distant areas.
• Some thinning of the character data is done to prevent the display becoming too complex. In some cases
and in some locations, the display contents may differ.
• The same place name, street name, etc. may be displayed multiple times.
Vehicle Mark Shows a Position Which is Completely Wrong
In the following cases, the vehicle mark may appear on completely different position in the map depending on
the GPS satellite signal receiving conditions. In this case, perform location correction and direction correction.
• When location correction has not been done
- If the receiving conditions of the GPS satellite signal is poor, if the vehicle mark becomes out of place, it may
move to a completely different location and not come back if location correction is not done. The position will
be corrected if the GPS signal can be received.
• When the vehicle has traveled by ferry, or when the vehicle has been being towed
Precautions
for driving
Just after the engine is started
If the vehicle is driven just after the engine
is started when the gyroscope (angular
speed sensor) correction is not completed,
the vehicle can lose its direction and may
have deviated from the correct location.
Wait for a short while before
driving after starting the engine.
Continuous driving without stopping
When driving long distances without stop-
ping, direction errors may accumulate, and
the current-location mark may deviate from
the correct road.
Stop and adjust the orientation.
Abusive driving
Spinning the wheels or engaging in other
kinds of abusive driving may result in the
system being unable perform correct detec-
tion, and may cause the vehicle mark to de-
viate from the correct road.
If after travelling about 10 km (6
miles) the correct location has
not been restored, perform lo-
cation correction and, if neces-
sary, direction correction.
How to cor-
rect location
Position correction accuracy
If the accuracy of location settings is poor,
accuracy may be reduced when the correct
road cannot be found, particularly in places
where there are many roads.
Enter in the road displayed on
the screen with an accuracy of
approx. 1mm.
Caution: Whenever possible,
use detailed map for the correc-
tion.
Direction when location is corrected
If the accuracy of location settings during
correction is poor, accuracy may be re-
duced afterwards.
Perform direction correction.

NORMAL OPERATING CONDITION
- Because calculation of the current location cannot be done when traveling with the ignition off, for example
when traveling by ferry or when being towed, the location before travel is displayed. If the precise location
can be detected with GPS, the location will be corrected.
Vehicle Mark Jumps
In the following cases, the vehicle mark may appear to jump as a result of automatic correction of the current
location.
• When map matching has been done
- If the current location and the vehicle mark are different when map matching is done, the vehicle mark may
seem to jump. At this time, the location may be “corrected” to the wrong road or to a location which is not on
a road.
• When GPS location correction has been done
- If the current location and the vehicle mark are different when the location is corrected using GPS measure-
ments, the vehicle mark may seem to jump. At this time, the location may be “corrected” to a location which
is not on a road.
Vehicle Mark is in a River or Sea
The navigation system moves the vehicle mark with no distinction between land and rivers or sea. If the vehi-
cle mark is somehow out of place, it may appear that the vehicle is driving in a river or the sea.
Vehicle Mark Automatically Rotates
The system wrongly memorizes the rotating status as stopping when the ignition switch is turned ON with the
turntable rotating. That causes the vehicle mark to rotate when the vehicle is stopped.
When Driving on Same Road, Sometimes Vehicle Mark is in Right Place and Sometimes it is in Wrong Place
The conditions of the GPS antenna (GPS data) and gyroscope (angular speed sensor) change gradually.
Depending on the road traveled and the operation of the steering wheel, the location detection results will be
different. Therefore, even on a road on which the location has never been wrong, conditions may cause the
vehicle mark to deviate.

REMOVAL
CAUTION:
• Before disconnecting the AV control unit and battery terminals, turn the ignition switch OFF and wait
at least 30 seconds.
• Before replacing AV control unit, perform READ “CONFIGURATION” to save current vehicle specifi-
cation. Refer to
AV-179, "CONFIGURATION (AV CONTROL UNIT) : Configuration List"
.
NOTE:
After the ignition switch is turned OFF, the AV control unit continues operating for approximately 30 seconds.
Therefore, data corruption may occur if battery voltage is cut off within 30 seconds.
1.
Disconnect the negative battery terminal. Refer to
PG-155, "Removal and Installation"
2.
Remove A/C switch (AUTOMATIC AIR CONDITIONING) or front air control (MANUAL AIR CONDITION-
ING).
