SiRF Gives GPS Muscle to Sanyo Gorilla Portable Navigation System

Innovative Design Reinforces SiRF’s Market Leadership in Mainstream Automotive GPS Market

SAN JOSE, Calif., May 20, 2005 – SiRF Technology, a leading provider of GPS enabled location technology, today revealed that its industry leading global positioning system (GPS) technology is providing the positioning capabilities for the SANYO Touch Gorilla NVDK790 DVD portable navigation system from Tottori SANYO Electric Company, Ltd., a Japanese division of the SANYO Group. SiRF’s SiRFStarIIe/LP GPS chip set is at the heart of the compact GSU-50 series GPS receiver module from Position Company, Ltd. of Japan, which Tottori SANYO builds into the NV-DK790 to bring advanced navigation capabilities to mainstream Japanese customers in a cost-effective package.

The SiRF GPS Chip set provides rapid, accurate and reliable information on location, speed and heading required by the system to drive the brilliant, realistically textured, threedimensional navigation application on the 336,960-pixel Gorilla touch-panel display. Already being hailed as the new standard for portable car navigation systems, the NV-DK790 features a SiRF Gives GPS Muscle to Sanyo Gorilla Portable Navigation System Page 2 DVD-ROM storage with highly detailed map data, DVD video player, music CD player, a TV tuner, FM transmitter (for playing audio through the vehicle audio system) and a large color LCD touch-screen display.

“Today’s announcement again demonstrates SiRF’s ability to deliver cost-effective, highperformance GPS solutions that meet the world’s most demanding requirements for automotive electronics,” said Kanwar Chadha, founder and vice president of marketing for SiRF Technology. “SANYO’s innovative portable navigation and entertainment system is a further validation of our vision of making GPS an integral part of daily lives of mainstream consumers. We will continue to work closely with Position Company and our other partners around the world to meet the product quality, delivery and support requirements of automotive customers.”

SiRF’s sophisticated GPS engine provides this new product outstanding navigation performance even in tough environments such as urban canyons and under foliage canopies. As a result, the NV-DK790 is able to accurately depict intersections, exit ramps and individual buildings with realistic 3D images under harsh conditions, as well as support real-time traffic information using Japan’s Vehicle Information and Communication System (VICS).

“Tottori SANYO has adopted SiRF’s GPS technology for its family of Gorilla navigation products because of its outstanding navigation performance and the ease of integrating the Position Company GPS modules across our product range,” said Yoshio Wada, president and chief operating officer of Tottori SANYO Electric Company. “With SiRF and Position as our GPS partners, we have a reliable positioning platform from which to grow our navigation system business.”

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

“Position Company is pleased to support Tottori SANYO’s GPS module requirements with SiRF as its GPS chip set partner,” said Kunihiko Kato, president of Position Company. “With SiRF as our GPS partner, Position Company is confident that we can meet Tottori SANYO’s requirements today and in the future with a product roadmap that will meet their most demanding positioning requirements.”
