Sorry, that wasn't really very clear in what I was trying to say. The RCD unit can't connect or control the phone via A2DP because it isn't actually Bluetooth capable. The cc9060 unit is what connects and streams the music from the phone so there's no settings available in the RCD510. You need to use the Bury kit for control.
Found this in the instructions pdf:
"To transfer your music via A2DP, your mobile phone has to be connected to the hands-free car kit in this mode. To do this, open the “Music Player” in your mobile phone and select a title. In the settings,
now select the option “Playback via...” or “... Bluetooth-Stereo-Headset” to play back the title on the HFCK. As the menu guidance of the mobile phone manufacturers is very different, the terms used for the
selection / the options may differ considerably. If you are not sure, read about this topic in the instruction booklet for your mobile phone.
The clef symbol then appears in the status line of the main menu and the music will be played back. If you now initialise the Music function via the voice control feature, the play back of the music will be interrupted.
If you select the Phone music item here, you initialise the Music Player. Here, the voice control is stopped and the play back of music continued. If you operate the HFCK up until this menu item via the touchscreen, then the play back of the music is not interrupted.
The Music Player
The following functions are available in the music player:
Back (title by title)
Skip (title by title)
Pause
Play
Stop
Via the loudspeaker symbol, you reach the plus and minus button for controlling the volume. The display reverts automatically after five seconds.
Using the red arrow, you are able to go one step back in the menu, or by clicking on it longer, return to the main menu straight away"
