INTRODUCTION
The Bluetooth system offers the following features:
• Seamless, wireless handsfree audio through a Bluetooth connection
• Digital audio interface with high qu ality, full-duplex, handsfree speech
• Speaker Independent Voice Recognition (VR)
• Voice-driven menu prompts
• Automatically mutes the radio
• Automatically pauses the CD player during calls
• Noise reduction and acoustic echo cancellation
• Compliance with Bluetooth Ha nds Free 0.96 and 1.0 profiles
• Audio through the door speakers

The Bluetooth system is standard fitment on DB9 an d is optional on the V8 Vantage. The control and
operation of the Bluetooth system is identical on a ll models, however the electrical architecture of the
cars audio does differ. To identify if Bluetooth is fitted, look for the LED Indicator located as shown
below:

Description
The Bluetooth Module controls the Bluetooth system on all cars. This module is a stand-alone unit,
which is not connected to any communication network on the car. The module is located on the
drivers side of the Instrument Pack (IP) ju st above the pedals (see page opposite).

The components of the system are:
1. Microphone
2. Bluetooth switches (steering wheel)
3. LED Indicator
4. Bluetooth Module
5. Amplifier (audio)
6. Switcher box (V8 Vantage only)

If a DB9 is installed with both the ‘in-car’ ph one and the Bluetooth systems and both systems are
active then the Bluetooth system will override the ‘i n-car’ phone system. An active call on the ‘in-car’
phone will be ended if a call is re ceived on the Bluetooth system or any of the Bluetooth menus are
used.

The Bluetooth module has been designed to meet the following parameters:
Parameter Units Nominal Lower Limit Upper Limit
Battery Voltage Volts N/A 10.5 16.0
Nominal Voltage Volts 13.2 12.2 14.2
Over Voltage (for 1 minute) Volts 24.0 18.0 25.0
Operating Current mA 225-300 <300uA (sleep) <1.5A
Room Temperature °C 25 15 35
Operating Temperature °C N/A -30 70
Storage Temperature °C N/A -40 85

INPUTS
The Bluetooth system relies on a number of signals it receives either from the car (via hard wiring) or
the users phone (via wireless Bluetooth communication network).

The Bluetooth system will only function if the us ers mobile phone has Bluetooth enabled and it is
‘paired’ to the car. For more information refer to the user’s guide for your mobile phone.

Keypad Steering wheel controls inpu t Variable resistance to earth

Screens
Some of the signals in and out of the Bluetooth modu le require screening to avoid interference being
picked up. A signal screen is a single wire running along side t he signal wire(s) which will absorb
electro magnetic interference (EMI).

The Bluetooth module on the V8 Vantage features only one screen so as to protect the signal from the
microphone. This screen wire is simply an earth but it is also used as a datum from which to reference
the microphone signal.

The Bluetooth module used on DB9’s features two screens. One is as on the V8 Vantage but is used
only as a screen (because the microphone signal from the amplifie r has two signal wires) and no
datum is required. The second screen on the module is used to screen the ‘Lineout’ signals to the
amplifier. As with the microphone scr een this wire is connected to earth.
