A couple posts I read say you have to swap the position of a couple fiber cables located behind the rear seat backrest to activate the Bluetooth. I see the same thing referenced in the install manual from BMW as shown in the picture below.
Do you know if this is this something I will need to do or will the coding make it work after I install the Mic and antenna?
