Horrible unit !

FM transmitters do work great, but not this one. My some and I have other FM transmitters that will override even a strong local station, giving pure music to listen to. This unit can't even cut through static on an empty station. Buy this unit only if you like to hear your tunes through a wall of intermittent static and interferance. Don't expect support from Belkin either. Even IF you get to talk to an English speaking person, they will have no idea how to help. Don't even consider this piece of junk.
