CSR has introduced of RoadTunes, a feature-rich, fully interoperable Bluetooth hands-free package for Personal Navigation Devices (PNDs) and in-car systems. Priced at $6, the reference design is designed to provide OEMs with a faster time to market. CSR estimated that the package can be integrated in an average of six weeks.

CSR’s reference design features full hardware and software components, including source code to allow designers to customize their designs. Based on CSR’s BlueCore5-Multimedia silicon, RoadTunes is a low-power, fully interoperable design with a RISC and DSP processor. The design incorporates both CSR Clear Voice Capture (CVC) and third-party echo cancellation technologies. BlueCore5-Multimedia also features Bluetooth v2.1 for pairing, and an audio CODEC with a signal-to-noise ratio of -95 dB.

Incorporating Bluetooth Embedded Control Interface (BECI) guidelines, RoadTunes allows for easy integration via a simple interface/API. It allows the simultaneous pairing of up to eight Bluetooth devices, and safely controls a vast array of functions through numerous voice prompts. It also offers multiple profile support (including A2DP, AVRCP, HFP, PBAP, DUN and SPP), so devices designed around RoadTunes can offer full Bluetooth connectivity including simultaneous audio, remote control of devices and hands-free operation.

RoadTunes enables three-way calling and automatic reconnection on start-up. With multi-profile support, RoadTunes provides users with the power to access a variety of functions including last number redial, mute, voice dialling, phone book and even call history download (SIM/Memory).

“The Bluetooth automotive market has experienced an enormous growth rate and we are confident that this will continue over the next two to three years,” said Rafik Jallad, vice president of CSR’s Automotive Strategic Business Unit. CSR’s RoadTunes is available in packages with external Flash memory, Plug n Go, and Plug n Go AEC-Q100 (automotive qualified package).
