I got the update. 07/2021.50. I have to say its a disappointment...I didn't get excited or feel emotional - even though BMW promised I would.
M SOUND CONTROL.
A unique sound experience for your BMW M3 and M4.
It's time to get excited: the engine starting sound has been refined, there is now clearer audible feedback when shifting gears and changing load cycles. Configure the sound characteristics however you like using the “Efficient” / “Sport” / “Sport Plus” engine settings and use the Sound Control button to further refine your settings, thus making the ///M driving experience even more emotional.
So you choose engine setting and then turn sound control on or off with any of them. This is the "customisation". WOW.
M TRACK MODE - Didn't we already have this? It just turns off all the drive and helps you focus on the track
