2. Description of the Related Art Conventionally, it is mounted on a vehicle such as an automobile,
2. Description of the Related Art A navigation system for displaying a current position of a vehicle, a route to a destination, and the like to guide a driver is known. Some of such navigation systems employ a satellite navigation system known as a Global Positioning System (hereinafter referred to as GPS), which receives signals transmitted from a plurality of geostationary satellites. Based on this received signal, the current position of the vehicle can be accurately calculated and displayed, and the route from the current position to the destination can be input. Therefore, the driver can safely drive to the destination by looking at the display.

As an example of the navigation system, there is one in which, in addition to course guide information, service display information used when displaying a weather forecast is stored in a database (Japanese Patent Laid-Open No. 372815/1992).
In the navigation system described in JP-A-4-372815, the traveling detection means detects traveling information such as direction, speed and position, and the environment detection means detects ambient environment information such as atmospheric pressure and illuminance near the traveling point, The contents displayed on the display are changed according to the traveling information and the environmental information, and the weather forecast is made from the atmospheric pressure as the environmental information.

[0004]

However, in such a navigation system, the weather forecast displayed is near the traveling point, and the weather forecast for the destination cannot be obtained. Usually, when a destination is input to the navigation to drive for a long distance, what is desired to be known is not the weather information at the current position but the weather information at the destination far from the current position. Therefore, conventionally, when it is desired to obtain the weather information of the destination, it is necessary to call the number 177 following the predetermined area code of the destination by using a car telephone or the like, and obtain the weather forecast as an information service by NTT. There was a problem that it took time.

The present invention has been made in view of the above problems, and provides a navigation system in which telephone information such as weather forecast at a destination can be easily used by setting the destination. Is intended.

[0006]

To achieve the above object, a navigation system according to the present invention has a controller, a display, an operation switch, a voice output means, a CD.
-When a ROM and a telephone circuit are connected and a destination is set by operating the operation switch, a predetermined station number of the destination is called according to the setting, and telephone information of the station number is output by the voice output means. It is characterized in that it is provided with a telephone information output means for outputting from.

[0007]

According to the navigation system having the above-described structure, when the destination is set by inputting the place name, the map screen or the telephone number, the route to the destination is searched and displayed on the display. At the same time, the telephone information at the destination is retrieved by the telephone information output means, displayed on the display and / or output as voice information from the voice output means.
