Development of INFONAVI-an in-vehicle navigation system with an information function utilizing radio pager

Daihatsu Motor is developing information and navigation systems aimed at small vehicles. The design goal of our system is to provide real time local information, good user interface and low cost. In this paper we present INFONAVI, an information dedicated navigation system with a one-way radio communication. The concept and system architecture are discussed. A data conversion algorithm introduced to utilize the paging networks as communication medium is explained. Finally, the configuration and functions of the sub-systems of INFONAVI are described.<
