We have developed a new, network-type navigation system and put it on the market as an Alpine product starting 2002/06. The following features distinguish this system from existing ones: (1) Seamless navigation: smooth networking with mobile phones and PCs expands the scope of navigation to beyond simply the interior of the vehicle; (2) Easy search of up-to-date information: access to server-side databases provides the most up-to-date information, with the implementation of fuzzy searches greatly improving the ease of operation; and (3) Mobile navigation: the use of mobile phones enables navigation even after getting out of the vehicle (such as when walking or using Park & Ride). The car navigation system has continued to develop rapidly since its first appearance in the early 90s. The addition of new features such as voiced route guidance, D-GPS, VICS (Vehicle Information and Communication System), DVD-ROM, and voice recognition has greatly improved the operability, accuracy, and data capacity of such systems, enabling the support of a safer and more comfortable driving environment. The advance of IT (Information Technology) within the past few years has also brought significant changes in the mobile environment. The explosive spread of mobile phones, especially, has promoted the integration of the automobile within a communication network. Such trends provide new possibilities for further enhancing the driving experience.
