CDs do have some advantages. I prefer to burn playlists to CD for use in my Crossfires because I don't mind leaving CDs in the car. Leaving a $400 iPod in the car is an invitation for theft. I could carry the iPod with me but then I have to carry it everywhere I go. Leaving an iPod in a hot car is also not good for it. If a CD gets hot and warps, I'll just burn another copy. If the iPod cooks, I'm out several hundred dollars.

Using CDs also means I don't have to replace the stock head unit (which sounds fine to me) nor do I have wires running all over the place to hook the iPod up to an after-market stereo. I don't need to keep an iPod charger in the car, either. The Crossfire is small enough as it is. I use plastic sleeves instead of jewel cases to cut down on the storage space required. I'd rather have a few CDs stored nicely in the center console than have a bunch of wires running everywhere.

I know there are people here who are very happy with their aftermarket head units and iPod hookups but it's not for me. I'll stick with CDs.
