iDrive/Nav, Do I REALLY Need It?
Now I've gotten to thinking... I think the navigation system is dandy, though I'd probably never really use it, and the iDrive gizmos are really fancy and fun (I'm a tech dood), but is it really all that great?
Are there some quintescential features you iDrive/Nav owners use the system for? Maybe I can't think of something right now and I'll kick myself later if I find a good reason to have had it. Then again, it's $2100 extra.
