When the FM Transmitter function is activated, the sound that would normally come through the unit speaker is instead routed to the FM frequency you select and broadcast at that frequency--then you tune your FM Radio to that same frequency and you will hear the sound through your car stereo speakers. Try to pick a frequency that seems to be 'empty'--where you may only hear static on the radio. Usually this will be near the low end of the FM scale. Also, this feature works MUCH better with the TMC antenna plugged in, as it uses this also as the broadcast antenna.
