I have an alpine, and they make an adapter that plugs into my ipod, and lets me control it from the deck (or remote). It's WAAAY better than an fm modulator. I've had if for a couple of years, I can't think of what the model # is, I'd bet you could get one now for a reasonable price. I'll try to find it. I don't have my truck today, but I'll look online and see if I can find it
