But... this is a pet peeve of mine... you should have the latest version at the time you take delivery of your vehicle.
I've had maps in all of my recent cars and, every time, I ask for the current maps software/firmware version. I then check it out and if not up to date, I ask about getting it. But even that's not enough as sales people will promise anything, even in writing, then get "overridden" when I try to make good on the promise, later.
I don't understand why this is so unreasonable and why it's not SOP for all dealers and auto manufacturers: I should have the latest maps at time of delivery.
