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.

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.

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.

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’.
