AUDIO SYSTEM

The audio system consists of the following components

• Audio unit

• Audio amplifier

• Front tweeters

• Front door speakers

• Rear tweeters

• Rear door speakers

• Subwoofer

• Steering wheel audio control switches

• USB interface

• Rod antenna

When the audio system is on, AM/FM signals received by the rod antenna are sent to the audio unit. The

audio unit then sends audio signals to the audio amplifier. The audio amplifier then sends audio signals to the

front tweeters, front door speakers, rear tweeters, rear door speakers and subwoofer.

Refer to Owner's Manual for audio system operating instructions.

SATELLITE RADIO SYSTEM

The satellite radio system consists of the following components

• Satellite antenna

• Satellite radio tuner integral to audio unit

When the satellite radio system is on, satellite radio signals are supplied to the audio unit from the satellite

antenna. The audio unit then sends audio signals to the audio amplifier. The audio amplifier amplifies the

audio signals before sending them to the speakers, tweeters and subwoofer.

Refer to Owner's Manual for satellite radio system operating instructions.

HANDS-FREE PHONE SYSTEM

System Operation

NOTE:
Cellular telephones must have their wireless connection set up (paired) before using the Bluetooth

telephone

system.
The Bluetooth

telephone system allows users who have a Bluetooth

cellular telephone to make a wireless

connection between their cellular telephone and the Bluetooth

control unit. Hands-free cellular telephone

calls can be sent and received. Some Bluetooth

cellular telephones may not be recognized by the Bluetooth

control unit. When a cellular telephone or the Bluetooth

with the Bluetooth

control unit. Different cellular telephones may have different pairing procedures, refer to

the cellular telephone operating manual.
Refer to the Owner's Manual for Bluetooth

telephone system operating instructions.

Bluetooth

Control Unit

When the ignition switch is turned to ACC or ON, the Bluetooth

control unit will power up. During power up,

the Bluetooth

control unit is initialized and performs various self-checks. Initialization may take up to 20 sec-

onds. If a phone is present in the vehicle and paired with the Bluetooth

control unit, Nissan Voice Recognition

will then become active. Bluetooth

telephone functions can be turned off using the Nissan Voice Recognition

system.

Steering Wheel Audio Control Switches

When buttons on the steering wheel audio control switch are pushed, the resistance in steering wheel audio
control switch circuit changes, depending on which button is pushed. The Bluetooth

control unit uses this sig-

nal to perform various functions while navigating through the voice recognition system.

The following functions can be performed using the steering wheel audio control switch:
• Initiate self-diagnosis of the Bluetooth

telephone system

• Start a voice recognition session

• Answer and end telephone calls

• Adjust the volume of calls

Microphone

The microphone is located in the roof console assembly. The microphone sends a signal to the Bluetooth

control unit. The microphone can be actively tested during self-diagnosis.

Audio Unit

The audio unit receives signals from the Bluetooth

control unit and sends audio signals to the audio amplifier.

The audio amplifier amplifies the audio signals before sending them to the speakers.

REAR VIEW CAMERA SYSTEM

• The audio unit supplies power to the rear view camera when the reverse signal is received.

• The rear view camera transmits rear view camera images to the audio unit when power is supplied from the

audio unit.

• The audio unit combines a warning message and fixed guide lines with an image received from the rear view

camera to display a rear view camera image on the screen.
