CSR has announced the launch of RoadTunes. RoadTunes is a fully interoperable Bluetooth handsfree package for Personal Navigation Devices (PNDs) and in-car systems. Designed to provide OEMs with a faster time to market, RoadTunes possesses less than six-week average integration time and is available from today at low cost. CSR's example design features full hardware and software components, including source code to allow designers to fully customise their end designs. Based on CSR's BlueCore5-Multimedia silicon, RoadTunes is a low power, fully interoperable design with 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 simple pairing and good audio CODEC with a signal to noise ratio of -95dB.

CSR has designed RoadTunes to allow OEMs to integrate Bluetooth connectivity quickly, enabling a faster time to market with an easy Plug-In concept. Incorporating Bluetooth Embedded Control Interface (BECI) guidelines, RoadTunes allows for easy integration via a simple interface/API. With almost no host MIPS required, RoadTunes reduces the stress of incorporating wireless connectivity in embedded and aftermarket automotive devices. The average time to integrate RoadTunes on a device is less than six weeks and does not require prior in-depth Bluetooth experience.

RoadTunes allows the simultaneous pairing of up to eight Bluetooth devices, and controls safely an array of functions through numerous voice prompts. As it also offers multiple profile support (including A2DP, AVRCP, HFP, PBAP, DUN and SPP), devices designed around RoadTunes can offer full Bluetooth connectivity including simultaneous audio, remote control of devices and handsfree operation. In addition to allowing users to pair up to eight devices, RoadTunes also 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). CSR's RoadTunes is available in packages with external Flash memory, Plug n Go, and Plug n Go AEC-Q100 (automotive qualified package).
