I'm a pretty big dummy and posted a thread almost the same as this one yesterday. If you are not trying to spend a ton of money on a new head unit with aux, I think there's another option. I know for my car (2002 chevy malibu) i'm thinking of buying a "GM12-AUX"
http://www.discountc...ail.aspx?ID=446It simply gives you an auxilary input for ur car. It's a much cheaper alternative then have'n to buy a new head unit, a wire harness blah blah blah. If you go to
http://www.crutchfield.com and then car audio and video (top left) u can plug in u car make and model and it will limit the items displayed to what u can use in ur car. then just click on "ipod & portable to factory radio" and it'll show u what you need for an aux input.
Down side is if u have a 5 disc CD changer in the trunk then that's prob. already hooked up and u'd hafta disconnect that. Guys let me know if i'm horribly wrong but those are my 2 cents.
******Quick question, don't mean to hijack the post, but to all u installers, how do u know how to get into the head unit? In my car there's a ton of plastic around the unit from the top of the cd player down to the cigerete lighter, do u just pry that off? Is ther a website with tutorials for this stuff? Lemme know thnx fellas.
