I'm not sure how lease deals look at the beginning of a new model year.
It's probably not worth waiting for, but considering it was a $2k add-on, I think I am going to explore options with BMW. It's frustrating when my car hasn't even left Germany yet plus the configuration screens showed the new iDrive when I built/ordered it
At this point, I would rather just have my order without the Nav and just wash my hands of all the superfluous tech anyway.
