i have to say dont go with the FM Modulator option... fm's suck for iphone/ipod, you dont get the same quality as you do with the aux plug and if your in a big city that has a lot of radio stations, its hard to find a perfectly clear channel...sound the sound becomes staticy
if you drive a bmw, my guess is you've got some money.. i would have a new deck installed (or install one yourself) you can buy a decent deck for 150-200 bucks (even cheaper at some places) install it yourself, cost you about 50 bucks, or have it installed at future shop or best buy for around 100 bucks... aux port is very much worth it.. you wont regret it.
i went this route and installed it myself.. the deck has a aux in it, so I can plug in my iPhone or my satellite radio, which ever i want.. it sounds amazing!
