Yes, it plugs into the the antena input for the stereo, so the FM modulated signal skips the radio (over-the-air) part of the transmission thus avoiding all the bad things (noise, echo, antenna loss, etc.) associated with it. The signal is still FM (frequency modulation) modulated, and the FM demodulator in the stereo's radio is still used, just like it would be for all signals coming through the antena.
