Information identifying the first radio source is transmitted from the vehicle to a remote processor. The processor monitors broadcast content of the first radio source on a web site.

Information identifying the second radio source is transmitted from the processor to the vehicle. When a quality of a broadcast signal from the first radio source received at the vehicle falls below a threshold quality level, tuning of the radio is switched from the first radio source to the second radio source.
