Well, just got a call from my salesman to tell me that my build is at 112 (Order scheduled for Production).
Apparently, I just sneak in as they got an e-mail Wednesday from BMW mentioning that the HUD is no longer available for all X3s and X4s.
If you are Status 111 (Order Accepted at AG) you should OK.
