Introduction

• Car-borne information system is an electronic
  system that provides all kinds of information for
  car drivers and passengers.
• It consists of car-borne information terminal and
  information service out of the car
• They are integrated by mobile communication
  technique and wireless network.
• It not only includes information display and
  entertainment device in the car, but also serves
  as a bridge among car, mobile commerce and
  traffic information service
