How to Read the Circuits
Below is a simple guide to what symbols mean on the circuit
diagrams. For some of the symbols there are descriptions as
to how they function.
Wires
Wires vary in size to allow diffe rent current to be carried. For
example a wire with a diamet er of 0.50mm (This is the
diameter of all the internal copper strands together) will
carry 11A (dependant on ambient temperature) whilst a wire
with a diameter of 2.00mm will carry 25A.
Twisted Wires
The ‘figure of 8’ shown on circuits as below denotes a
twisted wire and shows the wires that are twisted together.
A wire generates a certain amount of ‘electrical noise’ when
a current is passed through it. By twisting the 2 wires
together the ‘electrical noise’ is cancelled out on each wire
by the opposing wire. This is used more on sensors and
audio speakers.

Screened and Twisted Screen Wires
The signals through a wire can be affected by externally
generated electrical noise. To reduce the external
interference the wires are placed inside a conductive sleeve.
One end of the conductive sleeve is always open whilst the
other end can be terminated to a ground, to a component,
or left open.

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

OUTPUTS
V8 Vantage Outputs To Amplifier
The Bluetooth module in the V8 Vantage has three outputs sent directly to t he audio amplifier. These
outputs are:
1. Radio mute.
2. Speaker +
3. Speaker –

DB9 Outputs To Amplifier
As with the Bluetooth module in the V8 Vantage, the DB9 Bluetooth module has three outputs it
sends directly to the audio amplifie r. It should be remembered that all DB9’s feature a Linn amplifier
and therefore the Bluetooth output requir ements are different. These outputs are:
1. Radio mute.
2. Lineout -
3. Lineout +

The combination of these three signals allows the Linn Amplifier to control the audio output and
phone output through all or some of the speakers.

LED Indicator Outputs
The DB9 and V8 Vantage use the same LED Indicator (Bluetooth display) controlled in the same way
by the Bluetooth module. The output s from the Bluetooth module are:
• UIM LED - For Active Call LED (amber)
• UIM LED - For Active Call LED (blue)

These two outputs individually control the status LED’s (amber and blue) earth signal therefore
switching the LED’s on and off independently.

1. LED Indicator Outputs – System status
2. Steering column control switches

3. Integrated microphone (behind the rear view mirror).
4. Audio amplifier (not shown).


The Bluetooth system is voice activated on all models. When in voice recognition (VR) mode:
• Always speak normally. The system reacts to a normal voice pattern.
• Do not shout or speak erratically.
• When prompted to speak, speak after the ‘beep’.

5. Answer.

• When receiving a call – Press once to answer that call.
• When the system is not on a call- Press once to make a call using the last
number dialled
• While a call is in progress – Press once to toggle between hold and
resume. While on a call and after a ca ll waiting notification is received-
Press once to answer the waiting call.
• With two active calls – Press once to toggle between calls.
• During an active call – Press and hol d to switch audio between handsfree
and privacy modes.
6. Volume

• During a call – Press once to incre ase or decrease the Bluetooth speaker
volume.
• If the microphone is muted – Press once to un-mute.
• During a call – Press and hold to mute the microphone
7. End

• During an active call – Press once to end that call.
• When the system is in voice recogn ition (VR) mode – Press once to
cancel VR mode.
• When receiving an in coming call – Press once to reject that call.
• When in a pairing session – Press on ce to cancel that pairing session.
• During an active call(including mult i-party calls) – Press and hold to end
all calls.
• When the system is not on a call – Press and hold to terminate the
Bluetooth connection.
8. Talk

• During normal operation – Press once to initiate a voice recognition
(VR) session.
When a VR session starts, you will hear a prompt and then a short ‘beep’.
The ‘beep’ indicates that the system is waiting for a verbal command.
• A prompt is being played – Press on ce to skip the prompt and go to
the ‘beep’.
• Pressing and holding initiates the paring process.
