I haven't a good sight on the connectors but when you need the BMW type, with the round connectors, as far as I can see, the steeringwheelradiobuttons will not work with these.
You need 2 extra wires from the connector that goes into the radio, on the connector you will see 3 slots without wires, named 1, 2 and ground.
Make 2 long wires on 1 and ground and bring them to the connector that goes into the BMW car connector.
Have a good look where the 2 wires for the SWC are in the car connector. In the new BMW connector you have by the radio you will see that these 2 round pins are missing. What I have done is take 2 round pins out of the excisting connector that you don't need anymore. Connected to the 2 extra wires coming from 1 and ground from the radio. Put them in the new BMW connector and voila, works!
