I had mine done in Atlanta. The HUD turn signals worked but the trunk release inside still operates the small trunk to open but it does shut the large trunk when it is open. The tire pressure shows only a dashed line. He also tried the speed limit detection since I have lane departure warning but it did not work either.
I do like the other addition features as shown in the other post but I still wonder why BMW doesn't allow these settings. Those that are required by law I understand but the others I do not!
