DETECTING DEVICE FOR DATA ON BROADCASTING STATION FOR MOBILE UNIT AND BROADCAST RECEIVER FOR MOBILE UNIT

摘要

PURPOSE: To allow even a driver unaware of geographical information to select a channel of the receiver smoothly by allowing the driver to recognize a broadcasting station receptible at a position of a traveling vehicle in real time. CONSTITUTION: Channel data of a broadcast station receptible for each area are stored in a broadcast station data memory 144. A main arithmetic circuit 130 references the channel data based on a drive position of the self vehicle detected by a coordinate arithmetic section 118 and displays channel data of a receptible broadcast station at a current position onto a display device 136.
