A keyboard 20 for a driver to input predetermined information such as a current location and a destination; an external memory 22 for setting a magnetic disk 21 storing information (such as a map of a predetermined area and a gas station location); The speaker 26 is configured to output a voice by driving the voice generating unit 25 by the driving unit 24 based on the information obtained in the step, and the LCD 30 displays the information in a liquid crystal by the driving unit 28. In addition,
The sound generation unit 25 can be configured by a tape recorder that records various sounds, a sound synthesis circuit, or the like.

The receiver 14 receives the analog address signal transmitted from the transmitter 10, converts it into a digital signal by an A / D converter (not shown), and supplies the digital signal to the CPU 16 as address information.

The sensor unit 18 converts information detected by each sensor into a CP.
Supply as data to U16.

As described above, the keyboard 20 is used by the driver to input data on the current location and the destination, and the input data is supplied to the CPU 16. The keyboard 20 can be used in combination with an operation of a car stereo or the like.

The external memory 22 reads information such as a map stored in the magnetic disk 21 and supplies the information to the RAM 15 or the CPU 16. In the magnetic disk 21, for example, a map for each region (the metropolitan area, Tohoku, Shinjuku, Tiger's Gate, etc.) and information for each purpose (library, golf course, ski resort, hospital, etc.) are input. I have. Note that an optical disk, a magnetic tape, or the like may be used instead of the magnetic disk 21.

The audio signal generation unit 25 selects a predetermined recording tape based on information supplied from the CPU 16 via the drive unit 24, and notifies the driver of the selection. The LCD 30 displays information supplied from the CPU 16 by the drive unit 28.

Next, the actual operation of the embodiment configured as described above will be described with reference to FIG. Points a to h in advance
The transmitter 10 is installed in the.

For example, when the current value of the vehicle 11 is the point A and the user wants to go to the point B from here, the user operates the keyboard 20 to input the “current location A” and the “destination B”. The magnetic disk 11 to which the traffic information around the points A and B is input is set. When the magnetic disk 11 is set in the external memory unit 22, data is read from the magnetic disk 11 in the external memory unit 22 and sent to the CPU 16.

When predetermined data is input from the keyboard 20 and the external memory unit 22 to the CPU 16, the CPU 16 stores the data as shown in FIG.
A route from the point A to the point B is displayed on the LCD 30 together with the road maps around A and B. In the case of this embodiment, the first
Route (ab-c-de), second tool (ab-de)
g-h-e) and a third route (a-f-g-h-e) are displayed.

Next, when the route to the destination B is displayed, the driver instructs which route to select by operating the keyboard 20. It is also possible to input data on the traffic congestion status of each road into the external memory unit 22 for each time zone and day of the week, and to automatically guide the driver to arrive at the destination B in the shortest time based on the data.
