hold up, i have the answer on this one....
i bought a monster fm transmitter on amazon, it was around 30 bucks. but it is by far the best fm transmitter on the market. it literally gives me hd quality sound ( on my htc hd7) and i live in a moderatly populated area, so lots of radio stations. it is never fuzzy unless i am taking a long trip and then it is just a matter of changing the station. it has 3 preset stations which are programmable. no batteries required of course. and yes fm transmitters will work for any device with a aux out. has nothing to do with the OS.
