CSR plc (LSE: CSR.L) today confirmed that its world-leading BlueCore Bluetooth is incorporated in Nissan's advanced telematics system, christened 'CARWINGS'. The system, which offers enhanced GPS and entertainment features as well as integrated handsfree, is provided by Xanavi Informatics Corporation, an established partner of Nissan and CSR, and a leader in the telematics field. Currently, Nissan models featuring the integrated CARWINGS service include the new Nissan Fuga luxury sedan, the Lafesta minivan, the Tiida Latio compact sedan and the Tiida and Note compact hatchbacks.

The CARWINGS system aims to improve usability of in-car navigation. In addition to the in-car telematics / infotainment system which includes GPS navigation and TV in selected models, CARWINGS also offers a 24 hour telephone operator assistance for traffic information, vehicle location and journey planning

The Bluetooth connectivity provided by CSR's BlueCore, allows Bluetooth-enabled mobile handsets to connect wirelessly to the in-car system, making use of the handsfree capability and transferring downloaded applications and user information to the car unit. Users can also synchronise personal information including ID details, telephone directories and other contact information between a home computer, mobile handset and car system.

Anthony Murray, automotive product marketing manager, CSR commented, "The Japanese automotive market has recognised the convenience which Bluetooth brings to the vehicle. Early adopters like Nissan have leveraged this technology to add value to the in-car telematics and infotainment systems which extend the ubiquitous personal network for which the mobile phone increasingly holds the key." He added, "Bluetooth adds the flexibility for telematics and infotainment designers to remove the wired connections while ensuring compatibility with a maximum number of mobile phones and easy integration into new car models."

CSR BlueCore silicon is currently found in more than 60% of all Bluetooth products listed on the Bluetooth special interest group (SIG) qualifications website.
