I started a thread around getting the Sport HUD to be programmable by the M1 and M2 buttons. In my F82 I was able to configure the preferred HUD directly into the buttons, but for whatever reason BMW changed that and only allows the Sport HUD if you press the damn M mode button.

It's not difficult to hit M1 and then hit the M Mode button, but doing so means you lose the Road instrument cluster to enable the better HUD. Annoying.
