NOTE:
Noise resulting 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 t hat reflect off of mountains or buildings.
Noise InspectionINFOID:0000000005395318
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.

TELEPHONE
tooth cellular telephones may not be recognized by t
he Bluetooth control unit. When a cellular telephone or
the Bluetooth control unit is replaced, the telephone mu st be paired with the Bluetooth control unit. Different
cellular telephones may have different pairing procedures. Refer to the cellular telephone operating manual.
Bluetooth Telephone System Diagram
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 10 seconds. 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. For Bluetooth contro l unit location, refer to AV-35, "
Component Parts and Harness Connector Loca-
tion".
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 module uses this
signal 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
• Record memos
Volume Switch
Call volume can be adjusted using the audio unit volume switch.
Bluetooth Microphone
The Bluetooth microphone is located in the roof console assembly. The Bluetooth microphone sends a signal
to the Bluetooth control unit. The Bluetooth microphone c an be actively tested during self-diagnosis. For Blue-
tooth microphone location, refer to AV-35, "
Component Parts and Harness Connector Location".
Audio Unit
The audio unit receives signals from the Bluetooth control unit and sends audio signals to the speakers.
