This cable is for all radios that use the Icom C-IV control interface. On 10 February 2009, UK wireless chip company CSR announced it was buying SiRF in a share deal worth $136 million. A USB device driver for Windows for the IC-705 is available for download from. SiRFusion can then combine this real-time information with cellular base station and Wi-Fi access point location data, ephemeribased aiding information from the CSR Positioning Center (CPC) to generate accurate and reliable position updates. The SiRFusion platform integrates positioning from GNSS, terrestrial radio solutions such as Wi-Fi and cellular, and MEMS sensors including accelerometers, gyroscopes, and compasses. SiRFstarV chips, launched in 2012, are capable of tracking NAVSTAR, GLONASS, Galileo, Compass, SBAS, and future GNSS signals. Has GPS/Galileo baseband, LCD touch-screen controller, video input, 10-bit ADC and a high-speed USB 2.0. The SiRFatlas IV is a cheaper version of the very popular, but rather expensive SiRFPrima platform. SiRFatlas IV is a multifunction location system processor and is meant for entry-level Personal Navigation Devices (PNDs). The chips have been adopted by major GPS manufacturers, including Sony, Micro Technologies, Garmin, TomTom and Magellan.

The SiRFstarIII family comprises the GRF3w RF IC, the GSP3f digital section, and the GSW3 software that is API compatible with GSW2 and SiRFLoc.

SiRFstarIII architecture is designed to be useful in wireless and handheld location-based services (LBS) applications, for 2G, 2.5G, 3G asynchronous networks.
