Abstract
To provide a navigation system capable of easily switching between a portable terminal unit and a communication navigation terminal unit with an identical telephone number and also having considered a communication environment. A communication navigation system is comprised of an information server unit for controlling communication, a portable terminal unit and a vehicle terminal unit for performing navigation with the information server unit, and performs the communication by using a public switched telephone network circuit, and when switching each terminal unit to a communication capable state, it controls a position registration of each terminal unit by performing the communication among the information server unit, portable terminal unit and vehicle terminal unit so as to switch the communication capable state.
