I have a Pioneer head unit that has direct Ipod connection through auxillary inputs on the back, it's a USB connection that can either use the Ipods special USB or as I found out today, the USB that comes with our phones. It's able to access all the music on the phone (internal or SD)......I can't seem to get it to recognize playlists like I can my Ipod and the track listing is a little odd, but the audio quality is very good and it's a good option I think if you don't mind not having playlists.
