Wide applications potential
The RoadTunes reference design has been designed to satisfy the range of existing and emerging Bluetooth applications in automobiles. With its rich Bluetooth Profile application software support, and its simple 'BECI' API, the interoperability-proven RoadTunes is quickly integrated into embedded infotainment systems, or into aftermarket products including PNDs (portable navigation devices). A choice of packaging* ensures that developers have the right options, whether they are making low-cost PCBs or looking for a compact plug-on Bluetooth module.
First-mount systems
RoadTunes can be configured to provide sophisticated hands free calling support, as well as emerging applications such as streaming digital music from an MP3 player or handset into the vehicle's infotainment system. The DSP core includes CSR's powerful and proven CVC echo and noise cancellation algorithms - which may be tuned easily without affecting RoadTunes' Bluetooth qualification. BECI ensures easy integration with the vehicle's host processor, with a minimal load.
Aftermarket products
The complete hardware-plus-software solution provided by RoadTunes, with its BECI API and proven interoperability, ensures a rapid and simple path to market for manufacturers of automobile accessories such as PNDs or hands free kits. The choice of packaging ensures that OEMs and ODMs can choose the ideal solution for their needs, whether that is to embed the core onto their PCB, or choose a plug-on Bluetooth module.
Custom solutions
CSR will also provide users with the binary source code for the design, for custom applications (call your local CSR office for details). The built-in DSP core comes with CSR's own CVC echo and noise cancellation software. However, a wide variety of optional third-party software is available for the open core, including text to speech support from CSR eXtension partners.
Lifecycle software upgrades
DFU support provides options for upgrading RoadTunes firmware in the field.
