You need to use the OEM iPod cable with the Lightning adapter.
This has been discussed before.

I've read you can update it but on BMWs website it says that the update is only available on '10+ models. Read something as well about checking for an update option in "settings" which I didn't see either. Can anyone shed some light on this? Every thread I found is a bunch of people agreeing that it doesn't work for them either.
Thanks in advance,
