Also - Even if the adapter doesn't literally "cradle" the phone, you could take a short micro usb female -> male adapter cable, plug the female end into the adapter and the male end into your phone. Obviously wouldn't have the "snap-in" functionality, but the form vs. functionality standpoint is pretty moot at this point since BMW has chosen to ignore 60%+ of the smartphone market; referring to the Android user base.
