• When the selector lever is placed in R (reverse) or the CAMERA switch is pressed, power is supplied to the
cameras. The camera image signals supplied by the cameras are input to the around view monitor control
unit. The around view monitor control unit sends the signals to the AV control unit. The AV control unit dis-
plays the camera images on the display.
• Dimming signal is input from BCM to adjust the brightness of the display.
COMMUNICATION SIGNAL
AV control unit is connected to TCU via USB communication, and it receives the Telematics information
received by TCU and gives the display and sound output. Telematics operation signals and sound signals are
also sent to TCU.
Auto light adjustment function
Auto light adjustment function automatically dims/brightens the display according to the ambient light when the
lighting switch is in the 1st or 2nd position. Whether or not the display is dimmed when the lighting switch is in
the 1st position or 2nd position is determined by the output condition of the dimming signal output from the
BCM to the AV control unit. Even if the lighting switch is in the 1st position or 2nd position, the display may not
be dimmed depending on the ambient light sensed by the auto light sensor. For details, refer to

• Hands-free phone reception voice is output from the cellular phone through the AV control unit to the front
speaker via Bluetooth
®
communication.
• If the hands-free phone is used while the audio is ON and/or the voice guidance is being output, these
sounds are muted and only the reception voice is output.
Speech Sound Signal
Hands-free phone speech sound is transmitted from the microphone via the AV control unit and Bluetooth
®
communication to the cellular phone.
CARWINGS Reading Voice Signal
• In the case of the CARWINGS reading voice, the AV control unit receives text data from the NISSAN CAR-
WINGS Data Center through the USB harness and outputs them to the front speaker.
• If CARWINGS data is read while the audio is ON and/or the voice guidance is being output, these audio
sounds are muted and only the CARWINGS reading voice is output.
• Depending on the information from the NISSAN CARWINGS Data Center, not only the CARWINGS reading
voice but also background music may be output. In this case, audio output of the front speaker is turned
down 10 dB and then the CARWINGS reading voice is output.
Guide Sound Signal
• Voice signals output during the route guidance of the navigation system are output from the AV control unit
to the front speaker.
• If the voice guidance is output with the audio ON, audio output of the front speaker is turned down 10 dB and
then voice guidance is output.
• Adjusting the volume while the voice guidance is being output can change the volume of the guidance.
AUDIO FUNCTION
• The MP3/WMA playback function enables music to play for a long time: the user need not change the CD
during a long trip. The text display function is also adopted so that the title name and artist name of the ID3
tag/WMA tag can be displayed.
• Bluetooth
®
audio function is adopted to play music data in the portable audio via wireless communication.
• The adoption of the vehicle speed interlock sound volume function reduces the burden of the volume adjust-
ment by the difference between the noises when the vehicle is stopped or running. In addition, the vehicle
speed interlock sound volume function can perform ON/OFF setting and sound volume adjustment on a
scale of one to five.
MP3/WMA Playback Function
This function enables the playback of compressed music files, such as MP3 music files used for the most
widespread broadband music distribution and WMA music files played back with a music player generally built
in Windows
®
personal computers.
Vehicle Speed Interlock Volume Function
• The AV control unit receives the vehicle speed signal from the combination meter via CAN communication
and changes the sound volume in conjunction with the vehicle speed.
• Using the vehicle speed interlock sound volume function, ON/OFF setting can be carried out as preferred by
users, and sound volume variation caused by vehicle speed change can be adjusted on a scale of one to
three.
Bluetooth
®
Audio Function
• Bluetooth
®
audio function is adopted to play music data in the portable audio in wireless communication.
• Five units of Bluetooth
®
communication devices including audio devices and cellular phones can be regis-
tered to the AV control unit.
• When the Bluetooth
®
audio is connected to the portable audio through Bluetooth
®
, it can play the music data
in the portable audio.
• When the Bluetooth
®
audio is playing the data, operations of the other applications are as shown in the fol-
lowing table.

NAVIGATION SYSTEM FUNCTION
Description
• The AV control unit controls navigation function while GPS tuner has built-in map data, GYRO (angle speed
sensor), on the SD card.
• The AV control unit inputs operation signal with communication signal, through front display unit (touch
panel) and multifunction switch and steering switch.
• Guide sound is output to front speaker through from AV control unit when operating navigation system.
• A vehicle position is calculated with the GYRO (angle speed sensor), vehicle sensor, signal from GPS satel-
lite and map data stored on SD card, and transmits the map image signal (RGB image, RGB area, RGB
image synchronizing) to the display.
Position Detection Principle
The navigation system periodically calculates the current vehicle
position according to the following three types of signals.
• Travel distance of the vehicle as determined by the vehicle speed
sensor
• Vehicle turning angle determined by the gyroscope (angular speed
sensor)
• The travel direction of the vehicle 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, which is stored in the SD
card (map-matching), and indicated on the screen with a current
location mark. More accurate data is used by comparing position
detection results from GPS to the map-matching.

SYSTEM
The current position is calculated by detecting the travel distance
from the previous calculation point, and its direction change.
• Travel distance
The travel distance is generated from the vehicle speed sensor
input signal. The automatic distance correction function is adopted
for preventing a miss-detection of the travel distance because of
tire wear etc.
• Travel direction
The gyroscope (angular velocity sensor) and GPS antenna (GPS
information) generate the change of the travel direction. Both have
advantages and disadvantages as per the following descriptions.
Input signals are prioritized in each situation. However, this order of priority may change in accordance with
more detailed travel conditions so that the travel direction is detected more accurately.
Map-matching
Map-matching repositions the vehicle on the road map when a new
location is judged to be more accurate. This is done by comparing
the current vehicle position (calculated by the normal position detec-
tion method) from the map data stored in the SD card.
There is a possibility that the vehicle position may not be corrected in the following case, and when vehicle is
driven over a certain distance or time in which GPS information is hard to receive. Correct instructionly the cur-
rent location mark on the screen.
• In map-matching, several alternative routes are prepared and pri-
oritized in addition to the road judged as currently driving on.
Therefore, due to errors in the distance and/or direction, an incor-
rect road may be prioritized, and the current location mark may be
repositioned to the incorrect road.
If two roads are running in parallel, they are of the same priority.
Therefore, the current location mark may appear on either of them
alternately, depending on maneuvering of the steering wheel and
configuration of the road, etc.
