Car maker Audi will be incorporating Bluetooth technology into its cars from the end of this month in order to make life easier for drivers who need to make calls on the move.

CSR (Cambridge Silicon Radio) will be providing Audi with its BlueCore silicon technology for its Bluetooth-enabled TCU (Telematics Control Unit), which combines an embedded GSM and Bluetooth modules with a powerful CPU.

The system features an in-car rechargeable cordless Bluetooth handset that allows passengers to place and receive calls directly through the TCU Bluetooth link. The user is then able to transfer that call to the Bluetooth-enabled hands-free phone system in the car. Audi foresees this technology will become increasingly important in the near future as governments enforce more stringent rules over use of mobile phones in cars.

Industry experts estimate that up to 70 percent of all mobile calls are made from cars.

CSR is currently working on new Bluetooth automotive applications such as streaming video and MP3 files.
