載用ラジオ受信機。[Claim for Utility Model Registration] In a car radio receiver that has an auto-memory function that searches for receivable broadcasting station frequencies and stores this frequency data, broadcasts that are currently being received are included in the frequency data already stored in the memory. An identification means for identifying whether or not the frequency of the station is present is provided, and only when the identification means identifies that the frequency of the broadcasting station being received does not exist in the frequency data already stored, the frequency being received is determined. An in-vehicle radio receiver characterized in that it is configured to store memory.
