ABSTRACT:
A system is provided to prevent the generation of radio waves of local oscillation from an FM multiplex receiver 11 within a frequency band which adversely affects an FM radio 12 without providing an isolation buffer. The FM multiplex receiver 11 and the FM radio 12 are connected via a main controller 13. The main controller 13 discriminates whether or not the FM radio 12 is on. In the case that the FM radio 12 is on, the main controller 13 controls the tuning of the FM multiplex receiver 11 lest the tuning frequency of the FM multiplex receiver 11 should be set to a specified prohibited frequency.
