This might be a pretty dumb question to ask all of you 7-series BMW owners. But how come I see some of these E38's online, and even some of the same model, some have the general head unit area, but there's some here & there that have the screen navigation system but it's factory? I don't understand why I've seen some 740i's with and some without them. Any idea?
