CD AUTOCHANGERNLEL0385S06Testing Magazines and DiscsNLEL0385S06011. Confirm discs are installed correctly into the magazine (not upside down).
2. Visually inspect/compare the customer's discs with each other and other discs.
Identify any of the following conditions:
+Discs with a large outside diameter. [Normal size is 120 mm (4.72 in).]
+Discs with rough or lipped edges.
+Discs with excessive thickness [Normal size is 1.2 mm (0.047 in).]
+Discs with scratches, abrasions, or pits on the surface.
+Discs with grease/oil, fingerprints, foreign material.
+Discs are warped due to excessive heat exposure.
3. Slide/place the discs in and out of the various magazine positions.
Identify any discs and/or positions that require additional force for placement/ejection. If interference
(sticking, excessive tensions) is found, replace the magazine or the discs.
NOTE:
+Discs which are marginally out of specification (ex. dirty, scratched and so on) may play correctly
on a home stereo.
However, when used in the automotive environment skipping may occur due to the added vehicle
movement and/or vibration due to road conditions. Autochangers should not be replaced when
discs are at fault.
+Use a soft damp cloth to wipe the discs starting from the center outward in radial direction. Never
use chemical cleaning solutions to clean the discs.
Locking CD Changer Unit MechanismNLEL0385S0602CAUTION:
+Prior to removing a malfunctioning CD changer unit that will be shipped for repair, the changer
mechanism MUST BE LOCKED to prevent the mechanism from being damaged during shipping.

PrecautionsNLEL0510WARNING:
Do not attempt to disassemble the monitor. Parts of the monitor have high voltages that can result in
severe and dangerous electric shock.
CAUTION:
+Do not reverse battery connections.
+Do not attach unauthorized parts.
+Protect the unit from severe impact.
NOTE:
Before beginning repair, determine whether or not the unit is defective. Refer to ªThis Condition Is Not
Abnormalº (EL-432).

SEL504X
System DescriptionNLEL0512OUTLINENLEL0512S01The Navigation System (Multi-AV System) relies upon three sens-
ing devices in order to determine vehicle location at regular time
intervals.
1. Vehicle speed sensor: Determines the distance the vehicle has
traveled.
2. Gyro (Angular velocity sensor): Determines vehicle steering
angle and directional change.
3. GPS antenna (GPS data): Determines vehicle forward move-
ment and direction.
The data provided by the three sensing functions together with a
comparison of the mapping information read from the CD-ROM
drive permit accurate determination of the vehicle's current location
and subsequent course (map matching). The information appears
on a liquid crystal display.
This comparison of GPS data (vehicle position sensing) and map
matching permits precise determination of vehicle location.
SEL684V
Position Sensor Operating PrinciplesNLEL0512S0101The sensor determines current vehicle location by calculating the
previously sensed position, the distance traveled from this position,
and the directional changes occurring during this travel.
1. Distance traveled
The distance traveled is calculated using signals received from
the vehicle speed sensor. The sensor automatically compen-
sates for the slightly reduced wheel and tire diameter resulting
from tire wear.
2. Forward movement (Direction)
Changes in the direction of forward movement are calculated
by the gyro (angular velocity sensor) and the GPS antenna

+The enlarged intersection map may display a ªUnknown streetº message at some street intersections.
+Because of road configuration, etc. the guide may finish early. If this occurs, follow the marker to reach
your destination.
+Destination area side information (left side and right side) may differ from actual conditions because of
data error.
