I've seen the posts re the newly released NAV OS V27...is this the latest verson? And, is there any way i can find out if my newly ordered X3 (for a mid June Delivery, beiing built now) will come with this operating system "stock"? I ordered a NAV system, but will BMW use the latest OS available, as a matter of course, or is this an upgrade that can only be done after the fact?

Thanks all...
