Old car, old car radio, so I thought it would be perfect for listening to the iPod of my daughter and my USB key. First catch not so old as radio frequency search mode it starts right away on those taken. After a while I still manage to hang in free. Sound quality not great and very small volume but can be increased by the steering wheel radio. As I am not sure of the quality of my mp3 or my speakers I will not be satisfied me the difficult and this means its (light breeze). When reading the USB stick, you have to play songs in the order can neither advance nor retreat. However the remote control is small enough, you have to look before you press and it would be dangerous as driving while abstain. In short, what I wanted: to listen to my mp3 drive without earpieces, this transmitter is suitable. After that, I do not know if a price equal or even slightly above others offer a better sound quality.
