Locking CD Auto-Changer MechanismINFOID:0000000001328690
CAUTION:
 Prior to removing a malfunctioning CD auto-changer unit that will be shipped for repair, the changer mechanism MUST BE LOCKED to prevent the mech anism from being damaged during shipping.
 If a CD is jammed or unable to be removed from th e unit, do NOT lock the changer mechanism. If the
unit is to be shipped for repair, carefully package the unit to prevent vibration and shock.
DAMPER LOCK PROCEDURE
1. Eject and remove any CDs from the audio unit.
2. Turn ignition switch OFF. Wait until audio unit display is off and mechanism stops moving (mechanism
sound stops).
3. Press any one of the disc selection buttons once. When a display shows on the audio unit, press the
same disc selection button again within 5 seconds.
 The changer mechanism will lock itself within 10 seconds.
4. After mechanism stops moving (mechanism s ound stops), open the driver and passenger window, and
then disconnect negative battery cable.
NOTE:
After installing a new or remanufactured audio unit, switching the audio unit ON will automatically unlock the
mechanism. A special unlocking procedure is not required.
Removal and Installation of Audio UnitINFOID:0000000001328691
REMOVAL
1. Perform damper lock operation. Refer to AV-41, "Locking CD Auto-Changer Mechanism".
2. Remove cluster lid C. Refer to IP-10
.
3. Remove screws (6) with power tool, and remove audio unit with display and unified meter and A/C amp. from instrument panel.
4. Remove screws and remove audio unit.

With the ignition switch in ACC or ON, power is supplied
 through 10A fuse [No. 6, located in the fuse block (J/B)]
 to audio unit terminal 10.
Ground is supplied through the case of the antenna amp.
When the radio switch is turned ON, antenna signal is supplied
 through audio unit terminal 5
 to the antenna amp.
Then the antenna amp. is activated.
The amplified radio signals are supplied to the audio unit through the antenna amp.

NAVIGATION SYSTEM
The navigation system periodically calculates the vehicle's current
position according to the following three signals:
 Travel distance of the vehicle as determined by the vehicle speed sensor
 Turning angle of the vehicle as determined by the gyroscope (angular velocity sensor)
 Direction of vehicle travel as determined by the GPS antenna (GPS information)
The current position of the vehicle is then identified by comparing the
calculated vehicle position with map data read from the DVD-ROM,
which is stored in the DVD-ROM drive (map-matching), and indi-
cated on the screen as a current-loc ation mark. More accurate data
is judged and used by comparing vehicle position detecti on results found by the GPS with the result by map-
matching.
The current vehicle position will be calculated by detecting the dis-
tance the vehicle moved from the previous calculation point and its
direction.
 Travel distance Travel distance calculations are based on the vehicle speed sen-
sor input signal. Therefore, the calculation may become incorrect
as the tires wear down. To prevent this, an automatic distance cor-
rection function has been adopted.
 Travel direction Change in the travel direction of the vehicle is calculated by a gyro-
scope (angular velocity sensor) and a GPS antenna (GPS informa-
tion). They have both advantages and disadvantages.
More accurate traveling direction is selected because pr iorities are set for the signals from these two devices
according to the situation.
Map-Matching
Map-matching compares a current location detected by the method
in the “Location Detection Principle” with a road map data from DVD-
ROM stored in DVD-ROM drive.
NOTE:
The road map data is based on data stored in the DVD-ROM.
The vehicle position may not be corrected under the following circumstances and after driving for a certain
time when GPS information is difficult to receive. In th is case, the current-location mark on the display must be
corrected manually.

Type Advantage Disadvantage
Gyroscope (angular velocity sen-
sor) Can detect the vehicle's turning angle quite
accurately. Direction errors
may accumulate when vehicle is
driven for long distances without stopping.
GPS antenna (GPS information) Can detect the vehicle's travel direction
(North/South/East/West). Correct direction cannot be detected when vehicle
speed is low.
