SiRF Scores Another Win in Japan Automotive GPS Market With Design at Kenwood

SiRFstarIIe/LP-Based Toyocom GPS Module Powers High-End Kenwood Car Navigation System

SAN JOSE, Calif., Aug. 4 -- SiRF Technology, a leading provider of GPS enabled location technology, scored another victory in the highly competitive Japanese automotive GPS market today, announcing its industry leading global positioning system (GPS) technology is providing the integrated location capabilities for the new high-end Kenwood model HDM-555 HDD car navigation system. The SiRF SiRFStarIIe/LP GPS chip set is at the heart of the TCM-9016A2 GPS receiver module from Toyo Communication Equipment Co., Ltd. (Toyocom) of Japan that Kenwood is using to build high-performance navigation capabilities into their products more easily and bring them to market more quickly and cost effectively.

The SiRFstarIIe/LP GPS chip set's ability to provide rapid, accurate and reliable location, speed and heading information ensures that users of the Kenwood HDM-555 car navigation system get benefits of robust navigation, even in urban canyons, under dense foliage and in other challenging conditions. Being called the "Rolls Royce" of all-in-one car entertainment/information systems by early reviewers, the Kenwood HDM-555 is the world's first car navigation system with an integrated Apple iPod interface, enabling all iPod functions to be viewed and controlled from the large LCD display. The Kenwood HDM-555 is based on Microsoft Windows Automotive 4.2, features a 20-GB hard disk drive that can store the latest highly detailed map and point of interest data and thousands of MP3 and WMA music files, and can play DVD movies with DTS sound, music CDs and television programs.

"SiRF continues to build momentum in this most challenging market for automotive electronics, once again demonstrating our ability to work closely with value-added manufacturers like Toyocom to secure high-profile design wins," said Kanwar Chadha, founder and vice president of marketing for SiRF Technology. "Our market leading SiRFstarIIe/LP chip set offers a compelling choice to makers of car navigation systems, offering an easy, cost-effective way to integrate leading-edge GPS technology into their high-volume automotive products."

SiRF's high-performance navigation engine gives the Kenwood HDM-555 the highly accurate location information it needs to clearly depict intersections, exit ramps and individual buildings with realistic 3D images even under the harshest conditions and support real-time traffic information and re-routing capabilities using Japan's Vehicle Information and Communication System (VICS).

"The HDM-555 HDD car navigation system is an important product for Kenwood, catapulting us into the leadership position in this highly competitive market, and placing very stringent requirements on our suppliers to provide high performance and robust solutions," said Haruo Kawahara, president & chief executive officer, Kenwood Corporation. "The SiRF-based GPS receiver module from Toyocom offered us a cost-effective, highly accurate and reliable GPS subsystem we could easily integrate, backed by two outstanding technology suppliers."

As the industry standard for mainstream GPS, the SiRFStarIIe/LP is optimized for installed navigation devices such as the Kenwood HDM-555. With an embedded ARM7 TDMI microprocessor, the SiRFStarIIe/LP can incorporate additional functionality and features such as SiRF's adaptive TricklePower(TM) advanced power management technology for reduced power consumption or SiRF's SiRFDRive(TM) dead reckoning application for enhanced positioning accuracy and availability.

"Toyocom selected the SiRFstarIIe/LP for its first GPS receiver module product because of its outstanding price/performance and SiRF's reputation as a leader in GPS technology," said Yasuhiko Ikeda, deputy president of Toyocom. "Our partnership with SiRF gives us confidence we can continue to provide Kenwood with outstanding GPS technology solutions to meet their most demanding requirements today and in the future."
