Any update on whether this cradle (Part Number: 84212151038) works in the older eject boxes?

My thoughts:
Looking at the pictures & videos floating around, the connector on the underside of the cradle looks identical to the connector on the underside of the cradle for my old Nokia 6230i. This makes me think it would work on the older cars (E46) with the bluetooth phone integration AND on newer cars (my 120d) as the Nokia cradle works fine on both.
