    • PURPOSE:To select automatically the frequency of an optimum broadcast station at each location even when an automible makes a long distance drive by setting a frequency of a broadcast station receptionable at the district simultaneously in plural preset memories. CONSTITUTION:A position detection means is provided to detect a present position of an automobile. A controller discriminates, based on the detection means, which radio wave of which broadcast station the automobile at its present location receives. Then based on the discrimination, the frequency receptionable at the district is selected by a frequency setting means. Further, the frequency picked up by a frequency setting means is outputted in the preset memories. Thus, the frequencies of plural stations selected at the district are set in the preset memories. The set frequencies are tuning signals of a radio set or a TV set or the like. Thus, a driver, at any district, can receive a radio wave from a receptionable station at the district excellently by having only to depress a preset button.
