That is, the shared integrated receiver is a road-to-vehicle information tuner that receives, demodulates, and processes the road-to-vehicle information signal.
An M / AM demodulation circuit, a road-to-vehicle information signal processing circuit, and an FM tuner for receiving, demodulating, and data-processing an FM multiplex broadcast signal,

[0012]

In the present invention, the image signal processing circuit, the audio signal processing circuit, the display, the speaker, the controller circuit and the like are commonly used among the above-mentioned constituent circuits. Therefore, it becomes possible to obtain position information and wide-range traffic information from a nearby area to a wide area with a small and low-priced receiver.
