TELEPHONE
tooth cellular telephones may not be recognized by the Bluetooth control unit. When a cellular telephone or
the Bluetooth control unit is replaced, the telephone must 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.
During this time the Bluetooth ON indicator will flash until initialization is complete. If a phone is present in the
vehicle and paired with the Bluetooth control unit, NISSAN Voice Recognition will then become active and the
Bluetooth ON indicator will remain on. Bluetooth telephone functions can be turned off using the NISSAN
Voice Recognition system. For Bluetooth control unit location, refer to AV-43, "
Component Parts and Harness
Connector Location".
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 can be actively tested during self-diagnosis. For Blue-
tooth microphone location, refer to AV-43, "
Component Parts and Harness Connector Location".
Bluetooth ON Indicator
The Bluetooth ON indicator is located in the overhead console. The indicator will flash during power up while
the Bluetooth control unit is initializing. This process may take up to 10 seconds. If a phone is present in the
vehicle and paired with the Bluetooth control unit, the indicator will remain on to indicate that the system is
ready for voice commands. The indicator flashes during self-diagnosis. For Bluetooth ON indicator location,
refer to AV-43, "
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.
