I bought a second-hand 2006 Toyota Tundra SR5, my first car, from my mother's elder brother a month ago for USD 16,500（what about the price?), and get interested in everything car-related. Yesterday I found a FM transmitter as it is called (http://www.tinydeal.com/fm-transmit-px3k0y--p-4862.html) 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 suit my car?
