Bluetooth upgrade
 

Does anyone know what is needed to add Bluetooth in an 05 530i or is it even possible without having to upgrade to a CCC or CIC. It has a M-ASK system in it with iPod connector.

I like the setup suggested. The way it's set up I would have to buy the Aux in install and program it then install the Bluetooth board being that I do not have the Aux in already. Just making sure I captured what it was actually saying to do.
