I have the '09 diesel with the current IDrive Ipod adapter and can scroll A-Z for everything except album and genre(with I never use on the Ipod anyway due to mostly having only 2 genres, rock and country). My only wish would be to be able to scroll letter by letter like on the I-Pod itself instead of having to scroll through the entire playlist. Maybe this is what you're talking about? Not a big deal for me as I usually put it on random anyway, just a wishlist.
