Woohoo! Another douchebag DICE box screwing with the K-bus. Glad you got this sorted.

The stereo should not need to be unlocked. it determines that it is where it "belongs" by using the k-bus on the first power-up. if there are k-bus problems it will show as disabled. you *should* be good to go.

As far as solutions, I rock an OEM aux audio input. I don't do apple products so "integration" isn't really a concern for me in the first place. All BMW parts, cheap, clean install, music from my phone in the car. Done.
