Rapid Car Charger FM Radio Adapter Transmitter for Apple iPod
My car isn't that big, but I know I can hand my Ipod to anyone on the backseat and the sound won't stop coming thru the speakers, its pretty annoying to get it to certain frequency since you have to press the button a lot of times! but other than that no complains, the remote stopped working, but I don't mind because this was very cheap and the transmitter still works
