This is a good way to listen to your MP3 such as his car radio. Effective I use every day. The transmitter works well, but the display is not very readable. Small problem: the remote control that would be very handy ... if it worked properly. In fact I have to position myself well against the transmitter and sometimes I have to press several times before the signal passes. So convenient to skip the file, she would be more appreciated if it worked as it should!
