INTERNATIONAL SYMPOSIUM ON TELEMATICS 2002 October 1 1

2 Transition of car navigation in Japan • In 1987　Stored Map Database in CD-ROM

3 Transition of car navigation in Japan • In 1991　Released Car navigation system by various manufacturers – Adoption of GPS and Gyro sensor – From single purpose to multi purpose　→　The rise of commercial items ＧＰＳ Satellite Ceramic Gyro © 2002 Kiwi-W consortium

4 Birth of Ｎａｖｉｋｅｎ Format • Expansion of car navigation market • Expectation of entering into the navigation market by Audio makers which have no map data • Standardization of map disc, and entry the navigation market with map disc provided by map maker • Birth of Naviken Format Ver 1. 0 in 1988 • After adding more function, birth of Ver 2. 1 in 1995 © 2002 Kiwi-W consortium

5 Intensification of functional race • Quantitative race – Map • 1 -10 thousandth scale model of the whole country • Adoption of foot prints – 1400 cities – Search for destination • Search by phone number – Corporation 10 million cases – Individual 60 million cases • Search by address – 26 million cases CD-ROM plurality DVD-ROM © 2002 Kiwi-W consortium
