Rockbox 3.6 and beyond

yes, my car kit supports basically all the ipod's functions, most importantly browse (artist/album/playlists). Basically, I keep my iPod in the glove box at all times (except when bringing it inside to change whats on it), and being able to do wma/ogg on the iPod over car kit is great, but not outweighed by losing all "database" type functionality.

and as I said, i know rockbox has a database function, but its not really made to work with the ipod accessory support.
