I've got an iPod with the iTrip FM broadcaster attachment, and I'm not so hot on the iTrip. It can be a pain to find stations in the car, because first you have to locate a good unused station on the radio, then set the ipod to that station. In a car(even not in a car!) this can be quite a hassle. Then if you are on a road trip, your blank station won't stay blank for long. stations will come in and out and
Its a cool idea and I went for it but in practice I think its not for me. Luckily I happened to have a spare input on the back of my car stereo, so I mounted a RCA to Mini plug cable on it, and now I just plug that into my ipod's headphone out.
