CONSTITUTION:When the traffic information at 1620kHz is received, a first operation of a traffic information button 11 is performed. Since a frequency of the traffic information received at the last time is stored in a control microcomputer 6, the frequency of the traffic information received at the last time is read out to judge that the frequency received at the last time is 1620kHz or not. In the case that the frequency received at the last time is 1620kHz, a first button operation is performed in a short time less than two seconds. In the case that the frequency at 1629kHz is received in the different area, the first button operation is performed in a long time more than two seconds to receive that frequency. In this case, since 1629kHz is stored in the control microcomputer 6 as the frequency received at the last time, it is possible to receive the frequency at 1629kHz with the first button operation.
