I bought Hyundai Genesis Coupe, my first car, a month ago, and get interested in everything relevant to car. Yesterday I found a FM transmitter as it is called which is said to "broadcast music from your audio devices to your car stereo". I know FM is something about radio, and my car has been equipped with one. Then it seems that such a thing is not needed as for me. Or if the stuff has anything else good, please tell me. By the way, does it suits my car?
