A:Answer The BluClik is used to control the music source that is transmitting via bluetooth to wherever. (speaker, headphones, bluetooth receiver connected to car stereo, etc.).
The music source (any bluetooth capable phone, player, ipod etc) can be controlled by this device which attaches to the steering wheel. Control includes song skip, go back, volume up, volume down, play and pause.
In order to play through your car stereo, you would need a Bluetooth receiver connected via a Cassette Tape Adapter ,or a FM Transmitter, or wired directly to the stereo.
Good fortune to you, JD.
