Firstly, sorry I posted the wrong video on your other post... Here's the iDrive version (OK different car as this looks like a e90, but it's the same CIC version as the e89)....

Secondly I have the Samsung A70 (new current model) and mine pairs perfectly so I wouldn't worry about your S9+, it should pair fine
It has Pro Nav, Pro Radio, Comms option, Hi Fi Business media package so I presume so. It does try to pair. Will give it a good try soon. Just too busy at the moment which is frustrating.
Samsung S9+ paired straight away. What i was doing wrong was not entering 0000 in to the car and the phone at the same time. Once I did that the phone connected perfectly, phone book, messages etc. etc. Thanks for trying to help, much appreciated.
