Only an information output from a wireless terminal for mobile unit to a wireless base station is allowed in response to an operation of operating means of the wireless terminal for mobile unit. When only the information output from the wireless terminal for mobile unit to the wireless base station has been allowed by the operation of the operating means, an information output from the wireless base station to the wireless terminal for mobile unit is allowed in response to another operation of the operating means. The wireless terminal for mobile unit is constructed so as not to respond to another operation of the operating means during the predetermined time since the first operation of the operating means.

Wireless terminal for mobile unit

An object is to provide an anti-theft system for vehicles which is easy to operate and is capable of returning a stolen vehicle to its owner. A stolen vehicle is remote-controlled so as to make it impossible to restart an engine in response to a vehicle-theft report signal.

Anti-theft system for vehicles

A setting part is provided for setting a remote vehicle either in a valid state or in an invalid state, such that only a remote vehicle position transmitted from a remote vehicle set in the valid state is displayed on a display together with an own vehicle position.

Navigation apparatus for mobile vehicle and navigation communication system

In a mobile system and a mobile management system, when an emergency notification that an urgent car is approaching is transmitted from a base station to a general owner-driven car , the distance between the general owner-driven car and the urgent car is calculated on the basis of the current position of the general owner-driven car and the current position of the urgent car under the control of a CPU . If the distance is within a predetermined value, the base station notifies the driver of the general owner-driven car that the urgent car is approaching.

Mobile system and mobile management system

An information providing apparatus includes a terminal device in a mobile body for transmitting an information request signal and an information providing device for transmitting information data to the terminal device in response to the information request signal.
