ABSTRACT:
A mobile FM-multiplex-broadcast receiving device for receiving digital information (e.g., traffic information and general information) transmitted by FM-multiplex-broadcasts, which is capable of quickly obtaining a sufficient amount of necessary information by reliably selecting an optimally receivable FM-broadcasting station. This is realized by providing the receiving device with device for determining a correct reception ratio of digital information by calculating an amount of correctly received data to a total amount for each of FM-broadcasting stations and a driver for allowing a driver to select one of stations receivable with correct reception ratios greater than a certain preset value.
