BASIC OPERATIONS
RELATED TO AUDIO
 The majority of the audio malfunctions are the result of outside causes (bad CD/cassette, electromagnetic
interference, etc.). Check the symptoms below to diagnose the malfunction.
 The vehicle itself can be a source of noise if noise prevention parts or electrical equipment is malfunctioning.
Check if noise is caused and/or changed by engine speed, ignition switch turned to each position, and oper-
ation of each piece of electrical equipment, and then determine the cause.
NOTE:
 CD-R is not guaranteed to play because they can contain compressed audio (MP3, WMA) or could be incor-
rectly mastered by the customer on a computer.
 Check if the CDs carry the Compact Disc Logo. If not, the disc is not mastered to the red book Compact Disc
Standard and may not play.
Symptom Possible cause Possible solution
No image is displayed.The brightness is at the lowest setting. Adjust the brightness of the display.
The system in the video mode. Push to change the mode.
The display is turned off. Push to turn on the display.
The screen is too dim. The move-
ment 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 dark-
er or brighter than others.This condition is an inherent characteristic of liquid
crystal displays.This is not a malfunction.
Some menu items cannot be se-
lected.Some menu items become unavailable while the ve-
hicle is driven.Park the vehicle in a safe location, and
then operate the multi AV system.
Symptom Cause and Counter measure
Cannot playCheck if the CD was inserted correctly.
Check if the CD is scratched or dirty.
Check if there is condensation inside the player, and if there is, wait until the condensation is gone
(about 1 hour) before using the player.
If there is a temperature increase error, the player will play correctly after it returns to the normal
temperature.
If there is a mixture of music CD files (CD-DA data) and MP3/WMA files on a CD, only the music
CD files (CD-DA data) will be played.
Files with extensions other than “.MP3”, “.WMA”, “.mp3”, or “.wma” cannot be played. In addition,
the character codes and number of characters for folder names and file names should be in com-
pliance with the specifications.
Check if the disc or the file is generated in an irregular format, This may occur depending on the
variation or the setting of MP3/WMA writing applications or other text editing applications.
Check if the finalization process, such as session close and disc close, is done for the disc.
Check if the CD is protected by copyright.
Poor sound quality Check if the CD is scratched or dirty.
It takes a relatively long time before
the music starts playing.If there are many folder or file levels on the MP3/WMA CD, or if it is a multi session disc, some
time may be required before the music starts playing.
Music cuts off or skipsThe writing software and hardware combination might not match, or the writing speed, writing
depth, writing width might not match the specifications. Try using the slowest writing speed.
Skipping with high bit rate files Skipping may occur with large quantities if data such as for high bit rate data.

< SYMPTOM DIAGNOSIS >[BOSE AUDIO WITHOUT NAVIGATION]
NORMAL OPERATING CONDITION
Noise resulting from variations in field strength, such as fading noise and multi-path noise, or external noise from trains and other
sources, is not a malfunction.
NOTE:
 Fading noise: This noise occurs because of variations in the field strength in a narrow range due to mountains or buildings blocking
the signal.
 Multi-path noise: This noise results from a time difference between the broadcast waves directly from the station arriving at the
antenna and the waves reflected by mountains or buildings. Move immediately to the next song
when playingWhen a non-MP3/WMA file has been given an extension of “.MP3”, “.WMA”, “.mp3”, or “.wma”,
or when play is prohibited by copyright protection, the player will skip to the next song.
The songs do not play back in the
desired order.The playback order is the order in which the files were written by the software, so the files might
not play in the desired order. Symptom Cause and Counter measure

NAVIGATION SYSTEM
 Map-matching does not function correctly when a road on which
the vehicle is driving is new and not recorded in the map DVD-
ROM, or when road pattern stored in the map data and the actual
road pattern are different due to repair.
The map-matching function may find another road and position the
vehicle mark on it when driving on a road not present in the map.
Then, the vehicle mark may change to it when the correct road is
detected.
 Effective range for comparing the vehicle position and travel direc-
tion calculated by the distance and direction with the road data
read from the map DVD-ROM is limited. Therefore, correction by
map-matching is not possible when there is an excessive gap
between current vehicle position and the position on the map.
GPS (GLOBAL POSITIONING SYSTEM)
GPS (Global Positioning System) was developed for and is con-
trolled by the US Department of Defense. The system utilizes GPS
satellites (NAVSTAR), sending out radio waves while flying on an
orbit around the earth at an altitude of approximately 21,000 km
(13,100miles).
The GPS receiver calculates the vehicle's position in three dimen-
sions (latitude/longitude/altitude) according to the time lag of the
radio waves received from four or more GPS satellites (three-dimen-
sional positioning). The GPS receiver calculates the vehicle's posi-
tion in two dimensions (latitude/longitude), utilizing the altitude data
calculated previously with radio waves from four or more GPS satel-
lites (two-dimensional positioning) if radio waves were received only
from three GPS satellites.
Position correction by GPS is not available while the vehicle is stopped.
Accuracy of GPS will deteriorate under the following conditions:
 In two-dimensional positioning, GPS accuracy will deteriorate when altitude of the vehicle position changes.
 The accuracy can be even lower depending on the arrangement of the GPS satellites utilized for the posi-
tioning.
 Position detection is not possible when vehicle is in an area where radio waves from the GPS satellite do not
reach, such as in a tunnel, parking lot in a building, and under an elevated highway. Radio waves from the
GPS satellites may not be received when some object is located over the GPS antenna.
NOTE:
 Even a high-precision three dimensional positioning, the detection result has an error about 10 m (30ft).
 Because the signals of GPS satellite is controlled by the Tracking and Control Center in the United States,
the accuracy may be degraded lower intentionally or the radio waves may stop.

4. The trouble diagnosis initial screen is displayed, and then the
items of “Self Diagnosis” and “Confirmation/Adjustment” can be
selected.
SELF-DIAGNOSIS MODE
1. Start the self-diagnosis function and select “Self Diagnosis”.
- Self-diagnosis subdivision screen is displayed, and the self-diagnosis mode starts.
- The bar graph visible on the center of the self-diagnosis subdivision screen indicates progress of the trou-
ble diagnosis.
2. Diagnosis results are displayed after the self-diagnosis is com-
pleted. The unit names and the connection lines are color-coded
according to the diagnostic results.
NOTE:
 In case of connection malfunction of GPS or TEL antenna, diagnosis result follows “unit malfunction”
way to display.
 Replace AV control unit if “Self-Diagnosis did not run because of a control unit malfunction” is indicated.
The symptom is AV control unit internal error. Refer to AV-648, "
Exploded View".
- The comments of the self-diagnosis results can be viewed with a
component in the diagnosis result screen.
SELF-DIAGNOSIS RESULTS
 Check the applicable display at the following table, and then repair the malfunctioning parts.
 The self-diagnosis mode allows the technician to diagnose the connection in the communication line
between AV control unit and each unit and the internal operation of the AV control unit.
 Because the start condition of diagnosis function is a switch operation, the on board diagnosis function can-
not be started up if any malfunction is detected in the communication circuit between AV control unit and
multifunction switch.
