An apparatus and a method for automatically establishing a new wireless link, when the original wireless link between the apparatus and a commercially available FM radio receiver is interfered by other signal sources, thereby eliminating the need to manually configure both the target FM radio receiver and the apparatus to a suitable FM frequency. The apparatus modulates an audio signal on a selected frequency and transmits the resulting FM signal to the target FM radio receiver, scans an FM spectrum for available frequencies, selects one of the available frequencies as an alternate frequency, transmits a Radio Data System compatible command incorporating the alternate frequency to configure the target FM radio receiver to tune to the alternate frequency when reception conditions are poor.
