the XDV-P6 should be capable of reading any format that any AVIC can read...Double check with pioneers website...for an MSRP of 499, that changer should be able to read all the formats you can put in there and make you breakfast....if you want the same interface you get with a CD, then buy a dual layer dvd burner like i did on ebay for about 70 bux shipped, burn all your mp3's on a dual layer DVD-R, and screw the ipod...the drawback then is that you can't have the nav disc and your mp3 disc in at the same time...or you can get really exotic, and buy the XDV-P6, burn dual layer dvd's, and you will have roughly 50 gigs at your disposal
