A wireless FM repeater system for converting the audio signal from a portable audio source (e.g., iPod, MP3 player, a cell phone or satellite radio, etc.) and transmitting it to the FM tuner of a vehicle stereo system where access to a hard-wired input jack does not exist. The system includes a transmitter, coupled to the audio source, that transmits the audio source signals at a high frequency (e.g., 902-928 MHz, 2.4-2.483 GHz, 434/868 MHz) to a repeater located adjacent the vehicle's audio system antenna and wherein the repeater downconverts, without demodulation, the high frequency carrier and includes an FM transmitter that transmits the audio source signal, in compliance with government regulations, to the vehicle's audio FM system, via the vehicle's FM antenna, without signal degradation.
