Do I need an adaptor for Aux out?

[Fayewolf]

I have a car that comes with the aux out thing in the stock car stereo. i've been just using a simple cable (sorry, don't know what it's called), just from stereo to ipod with no problems. I tried to plug into the iphone, it sorta fits, but sound was not coming out. I searched the forums, and I thought people with aux output was able to use the cable without adaptor, am i mistaken?

Well, unfortunately one of the downfalls of the iphone is the recessed headphone jack. Apple sells an adapter that's slim enough to fit in the jack. Or you could just make one out of a 1/8" mini cable like I did :2cool: (just trim some of the rubber shielding from one of the ends till it fits)
