AV-376
< 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
NAVIGATION SYSTEM
System DiagramINFOID:0000000003765835
System DescriptionINFOID:0000000003765836
DESCRIPTION
 The navigation system can be operated by display (touch panel), multifunction switch or steering switch.
Each operation signal is input to AV control unit. AV control unit communicates with NAVI control unit via AV
communication, and controls the navigation system.
 Guide sound during the operation of the navigation system is output from NAVI control unit to front speaker
through AV control unit and BOSE amp.
 NAVI control unit calculates the vehicle location based on the signals from GYRO (angle speed sensor),
vehicle sensor, and GPS satellite, as well as the map data from Map DVD-ROM. It transmits the map image
signal (RGB image, RGB area, and the synchronizing RGB image) to display through AV control unit.
POSITION DETECTION PRINCIPLE
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 map DVD-
ROM, which is stored in the DVD-ROM drive (map-matching), and
indicated on the screen as a vehicle mark. More accurate data is
judged and used by comparing vehicle position detection 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 detected because priorities 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 Map
DVD-ROM stored in DVD-ROM drive.
NOTE:
The road map data is based on data stored in the map 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 this case, the vehicle mark on the display must be cor-
rected manually.
 In map-matching, alternative routes to reach the destination will be
shown and prioritized, after the road on which the vehicle is cur-
rently driven has been judged and the vehicle mark has been repo-
sitioned.
Alternative routes will be shown in different order of priority, and
the incorrect road can be avoided if there is an error in distance
and/or direction.
They are of the same priority if two roads are running in parallel.
Therefore, the vehicle mark may appear on either of them alter-
nately, depending on maneuvering of the steering wheel and con-
figuration of the road.

(North/South/East/West).Correct direction cannot be detected when vehicle
speed is low.

< FUNCTION DIAGNOSIS >[BOSE AUDIO WITH NAVIGATION]
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.

that may have occurred before the self-diagnosis start because of this situation.
The frequency of occurrence in error history is displayed in a count up manner. The actual count up method
differs depending on the error item.
