The buttons on the wheel are standard regardless of bluetooth, the grill fro the mic is also standard, is there anything behind it?

If you have Nav there will be an option for 'Telephone' if the module is installed, this will not be there if it's not installed.

If you have a MID and not Nav then the MID will have 3 buttons on the right, the center one will have two symbold, a phone and 'TEL'.

If you have an IRIS unit then they do not spport the phone.
