My X3 comes with the basic headunit (S663 BMW professional radio) without Bluetooth , not even for phone calls. I would like to be able to retrofit bluetooth.

At the trunk I cannot see a combox unit there. Maybe it is integrated with the headunit? I dunno. My iDrive looks like NBT.

How would I go about checking out if it is possible to retrofit Bluetooth to the system for calls and music. My steering wheel has the buttons. I wouldn't like to add those couple of features if possible.

thanks
