I have a 2004 (new body style) Supercrew with a single CD head unit. It has the AUX button on it. Can I get a harness to hook an MP3 player up to it?

 

I could be wrong but I think you need some sort of converter or something before you can use your IPod.

My suggestion, buy a new head unit =)

I just got the Alpine 9883 with high-speed IPod connection and I absolutly love it. No lag or anything.
