I'm looking for an FM Modulator/Transmitter other than those two. I have the iTrip, do not like it. Had the newer tunecast, that whistle annoyed me to hell. Now I have the older style Tunecast. I love this thing, but the small amount of channels is killing me. I just drove through NYC with this, and realized how useless those channels are. Does anyone know of a good FM transmitter that has the same amount of channels (or close to) as the iTrip, and not the annoying high pitched tone from the new tunecast? Thank's for the help.
