MY10 bluetooth audio control q

[ab012]

Hi everyone! Long time lurker, looking forward to getting the MY10 GT very soon:)

One thing i am currently very confused about - with the MY10 one can stream music from an iphone to the car's audio system. However - what is not clear to me is what exactly is controllable via the car touchscreen. I have heard from "volume only" to "everything - tracks, playlists etc". If anyone can clarify for me what it can actually do it will be greatly appreciated!

thanks in advance!~
