Justonemore, all you need to do is get an 'iPod adapter', which plugs into the CD changer port. This allows you to plug any device with audio out directly into your car stereo system. They have difference names for these adapters, but Cruthfield should have them as well. I have one in my car, and used it a lot with my CarPC. Now I use it with my Dell Axim X50V, so I can use it as my mp3 player. Other options are FM transmitter (sucks), or upgrade your head unit.
