The carwhisperer project...
Once the connection has been successfully established, the carwhisperer binary starts sending audio to, and recording audio from the headset. This allows attackers to inject audio data into the car.

Ideally, the carwhisperer is used with a toooned dongle and a directional antenna that enhances the range of a Bluetooth radio quite a bit. (more)
