Undocumented in that there is no information that definitively informs the shopping buyer for determining what components come with options. Read an X5 brochure, look on-line at BMWUSA, ask any dealer and none will tell you. I wanted a USB port for the simple purpose of downloading music the the car's HD. had I known it would come with my Tech package, I never would have ordered 6FL (have no use for it). I even told my salesman I wanted a USB to download music and he told me I needed 6FL (which we NOW know was incorrect). Is it possible he lied to sell me a $400 feature I did not need? yes, but given the extensive discussion and absence of any "documentation" informing buyers about these features, we are concluding that no one knows - definitively. We have at least 4 or 5 threads, since I joined the BMW forums in January, discussing these points and no one has 100% concrete factual information. So far, it has been speculation and process of elimination (with posts like PasPar2's just above). Paspar2, others and I have been bouncing this around for months.

This is why PasPar2 posted: "for whom ever stumbles upon this old thread: just took delivery on my my 2011 50 with tech and no 6fl and I DO have a usb in the glove...."

The manual may cover the features but it does not tell you which features come standard, which are stand alone options and which features come with other features. For example, no forum members seem to have seen anything that says the glove box USB is a feature component of the navigation system - either Nav stand alone or as part of the Tech package. After much forum bantering around, we are down to posting what we get in our vehicles (relative to these features) based on the options we ordered. Thus --> undocumented
