It certainly supports some of the accessory protocols as I can dock it and control it (play/pause/next/back) from my Ikon Radio. I assume you need more?
Are the protocols used by cars documented anywhere?

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.
