In a word, yes, but only probably every three years or so.
(oh, and if you think $200 is bad, they used to charge $400 for it)

Roads - even major roads - change in my area quite often, but that's rare for most folks.

It does take a year or more for changes to be reflected in the data sources, and there's a lot of effort in collecting those data. Someone didn't create it for free, so I don't expect to get it for free, either.

It's true that some NAV device makers offer "free lifetime updates" - for their little tiny awkward display that always makes you look like a tool driving down the road.

I prefer a large, integrated display, but I do understand those that want a newer device with maybe more features, it's cheap, etc. Suit yourself.

It probably would not kill BMW to make map updates free, though..
