Regarding the premium sound, see attached pic from online build status as to why I thought they might have "thrown in" Enhanced Premium....
Anyway, so keeping in mind I am coming from an '09 X6 with Premium Sound that I have listened to daily for 3 years... and now in the '13 X6, it sounds markedly more crisp and clean. Not really any louder but much, much cleaner. Noticeable difference.
So my thought is I didn't really get a free option and either a) BMW has upgraded or changed suppliers of some components, which I'm sure happens all the time or b) placebo effect from having a "clean new car"
Regarding the front fog light surrounds, they are still silver... so if they're supposed to be black, that is not addressed yet.
I will try to get some additional pictures taken this week if interested.
I just ordered my media snap-in adapter today, too, to replace the older one that doesn't support BMW Apps.
