I am able to do that.

The vehicle information includes traffic information such as road congestion and construction regulations, and information about living roads such as shopping streets and gourmet streets. Have Also,
The vehicle information includes data on the roads to which the information is provided.

When an input instruction for vehicle information display is given from the operation device 8, the signal processing device 4 causes the FM broadcast receiver 9 to operate.
Vehicle information received by the radio wave beacon receiver 11
Vehicle information or optical beacon receiver 1 received by
The vehicle information received by the vehicle 4 is temporarily stored in the internal memory, and the position on the map displayed on the screen of the display device 7 is calculated from the position data of the received vehicle information. The type of vehicle information is discriminated, and each symbol corresponding to the type of vehicle information is displayed at each position on the map.

At this time, for example, when a traffic information display command is given, the signal processing device 4, as shown in FIG. 3, is displayed at each predetermined position on the map where the current position P of the vehicle is displayed. The symbols A ₁ , A ₂ , A ₃ , B, and C of the respective received traffic information are displayed. Symbol A indicates a traffic jam location, symbol B indicates a traffic regulation location, and symbol C indicates a road closure.
