ABSTRACT:
A method is provided for suppressing interference in a motor vehicle radio that is capable of executing a seek/scan function. Interference may occur from signals generated by a source of time varying signal that operates in the motor vehicle at a predetermined operating frequency. The method comprises the steps of sending a message indicating initiation of a seek/scan function. In response to this message, the operating frequency of the source of time varying signal is cycled between the predetermined operating frequency and an adjusted operating frequency.
