Zusammenfassung:PURPOSE:To reduce the trouble of rewriting a receivable frequency in a memory and to improve merchandise property by controlling the start of an automatic searching/memory means which automatically extracts the receivable frequency from a frequency area for which a reception means covers and which stores the receivable frequency. CONSTITUTION:A control means 24 activates the automatic searching/memory means 12 when the reception means 10 is not used and the travel distance of a vehicle is more than a prescribed value based on a detection signal from a unusing detection means 18 and a travel distance detection means 26. The receivable frequency which the automatic searching and memory means 12 selects is automatically altered by adjusting it to the area. Thus, the trouble of rewriting (updating) the receivable frequency in the memory can be reduced and the merchandise property can be improved.
