I'm about to buy a 30GB iPod, and my car ('07 Jetta) has a built in iPod adapter. What do I need in order to play music in my car from my iPod? I've tried searching and looking through everything on Apple.com but I can't figure it out. Thanks!
an auxilary hook-up is just a headphone jack sized hole...usually found under a little flap of rubber or plastic to keep dirt and stuff out. it would probably say "aux" on it. if this is the case, you can purchase a short cable with headphone hook-ups on either end...one end goes in the aux and one end goes in the headphone jack of the iPod.
a true adapter would probably be more than one little hole. if this is the case, you'd want to do as puckhead said and contact your dealer to be sure you're getting the proper cable.
