Our 2015 F56S currently has Next 2016-1 maps installed.

We got a brand new 2016 Clubman S loaner car for a week, and it had way more detailed maps, with a lot of detail on topographical features and the like. I can't imagine that the Clubman has a different nav system, but perhaps it runs a different map system. Does anyone know what the difference is?

Could a map update bring the additional detail?
