A unit 251, and a voice output unit 252 composed of a speaker or the like for outputting the user input data or route guidance to the voice.

The road information guide process by the road guide system and the vehicle navigation apparatus according to the prior art configured as described above will be described.

First, a road guidance information service provider constructs a DB necessary for constructing road guidance information including an electronic map DB 121 corresponding to a physical road form, a node DB 122, a link DB 123, and the like, Manage the DB by updating the DB according to the change of road condition after each DB construction.

On the other hand, the operator server 100 that controls the entire system, when the road information guide service subscriber information received through the user information receiving unit 110 is newly received, updates the user information DB 124 newly.

The operator server 100 provides the electronic map DB 121 and the node to provide road guidance information to a user subscribed to the service on the basis of the user information DB 124 to guide road information to a road information guidance service subscriber. From the DB 122 and the link DB 123, the data necessary for serving the user is extracted and outputted to the transmission data processing unit 130.

The data necessary for serving the user includes data necessary for constructing a digital electronic map displaying the shortest nodes and links forming a route to a predetermined starting point and destination selected by the user.

The transmission data processing unit 130 processes the road guide information into data of a predetermined type required by the user based on the user information and outputs the data to the data transmission unit 140.

The data transmission unit 140 transmits the road guide information data processed by the transmission data processing unit 130 into data of a predetermined type required by the user to a user device through a predetermined transmission medium.

According to the above process, the road guide information data transmitted from the operator's road information guide system is received through the data transceiver 220 of the user's vehicle navigation device. The received road guide information data is stored in the storage unit 260 through the control unit 200.

When the user inputs desired destination information through the user input unit 210 to head to a predetermined destination, the controller 2000 may determine the current location of the user detected by the user location detector 230 and the destination input by the user. The road guide information data for the route is extracted from the storage unit 260 in which the navigation data and the display guide data required for the guide are stored and output to the road guide information processor 240.
