I've one of the press release 6 GC with LEDs but it's doesn't have the beam select thing but later cars I'm told have it. It might be as simple as an age thing and wasn't approved when the cars were built
I know of an M6 that was delivered this month that does not have Selective Beam. The owner has raised an issue with BMW because the literature says it should have. There are people that have reported getting it enabled by third party coding specialists.
