It's really nice to have a transmitter that is powered by the car and can also charge the ipod. It's pretty easy to use and dial in new stations. Non of that matters if the signal from the unit is too weak to provide a strong signal and that is the case here. I can't get a strong enough signal out of it to drive clear sound out of the radio, independent of the station that I use. Unfortunately, I have to give this a very low rating for that reason.
