RELATED TO NOISE
The majority of the audio concerns are the result of outside causes (bad CD, electromagnetic interference,
etc.).
The following noise results from variations in field strength, such as fading noise and multi-path noise, or
external noise from trains and other sources. It is not a malfunction.
• Fading noise: This noise occurs because of variations in the field strength in a narrow range due to moun-
tains or buildings blocking the signal.
• Multi-path noise: This noise results from the waves sent directly from the broadcast station arriving at the antenna at a different time from the waves which reflect off mountains or buildings.
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 opera-
tion of each piece of electrical equipment, and determine the cause.
NOTE:
The source of the noise can be found easily by listening to the noise while removing the fuses of electrical
components, one by one.
Type of Noise and Possible Cause
RELATED TO HANDS-FREE PHONE
Occurrence condition Possible cause
Occurs only when engine is ON. A continuous growling noise occurs. The speed of
the noise varies with changes in the engine speed.
• Ignition components
The occurrence of the noise is linked with the operation of the fuel pump. • Fuel pump condenser
Noise only occurs when various
electrical components are oper-
ating. A cracking or snapping sound occurs with the op-
eration of various switches.
• Relay malfunction, audio unit malfunction
The noise occurs when various motors are operat-
ing. • Motor case ground
•Motor
The noise occurs constantly, not just under certain conditions. • Rear defogger coil malfunction
• Open circuit in printed heater
• Poor ground of antenna feeder line
A cracking or snapping sound occurs while the vehicle is being driven, especially when
it is vibrating excessively. • Ground wire of body parts
• Ground due to improper part installation
• Wiring connections or a short circuit
Symptom
Cause and Counter measure
Does not recognize cellular phone connection (No connection is
displayed on the display at the guide). Some Bluetooth
® enabled cellular phones may not be recognized
by the in-vehicle phone module.
Refer to “RELATED TO HANDS-FREE PHONE (Check Compati-
bility)” in AV- 1 0 8 , "
Symptom Table".
Cannot use hands-free phone. Customer will not be able to use a hands-free phone under the fol-
lowing conditions:
• The vehicle is outside of the telephone service area.
• The vehicle is in an area where it is difficult to receive radio
waves; such as in a tunnel, in an underground parking garage,
near a tall building or in a mountainous area.
• The cellular phone is locked to prevent it from being dialed.
NOTE:
While a cellular phone is connected through the Bluetooth
® wire-
less connection, the battery power of the cellular phone may dis-
charge quicker than usual. The Bluetooth
® Hands-Free Phone
System cannot charge cellular phones.

SYSTEM
• AV control unit calculates the vehicle location based
on the signals from GYRO (angle speed sensor), vehi-
cle sensor, and GPS satellite, as well as the map data from map SD-card. The vehicle location is displayed
on the 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 SD-card (map-matching), and indica ted 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 becaus e 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 Princi ple” with a road map data from map
SD-card.
NOTE:
The road map data is based on data stored in the map SD-card.
The vehicle position may not be corrected under the foll owing 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.
SEL684V
Type Advantage Disadvantage
Gyroscope
(angular velocity sensor) 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.

• In birds-eye view, the blind spot area is displayed in black to show the border of the camera images. In addi- tion, red fixed lines are displayed in the 4 corners of the vehicle icon. After pressing the CAMERA switch for
the first time or placing the selector lever in R (rever se) for the first time, the blind spot area is highlighted in
yellow for 3 seconds and the red fixed lines blink five times.
• With the selector lever in any position other than R (reverse), the around view monitor screen display is can- celled 3 minutes after pressing the CAMERA switch. The screen returns to the AV control unit display.
• With the selector lever in R (reverse) position, the around view monitor screen display remains on con- stantly. To return to the AV control unit display, place the selector lever is in any position other than R
(reverse).
• If camera image calibration is incomplete, the applicable camera position is indicated as an error on the birds-eye view display.
NOTE:
Calibration is necessary when replacing each camera or when replacing around view monitor control unit.
Around view monitor screen transition
Front View
• The front view image improves the visibility of obstacles in front of the vehicle and assists driving by display-
ing images from birds-eye view and front-side view.
• The front view image displays the vehicle width guiding line and vehicle distance guiding line, in addition to the predictive course line according to the steering angle.
• If the steering angle is within approximately 90 degrees, t he predictive course lines on the left/right side are
displayed. If the steering angle exceeds approximat ely 90 degrees, only the predictive course line on the
outside is displayed (opposite side of steering direction).
• The around view monitor control unit receives the steering angle signal from steering angle sensor via CAN
communication, and controls the direction and distance of the predictive course line.
• ON/OFF setting of predictive course line can be performed using CONSULT.
