I did just remember one complaint - the navigation arrival time calculation appears to be entirely unsuited for Norway.
Say you're in a remote mountainous region, low traffic, speed limits of 80 (~70%), 70 (~10%), 60 (~10%), less (~10%), some roads geographically limited to less... how on earth do you arrive at a projected average speed of ~79km/h
Once back in .dk and .de the projection was accurate again.
There was another thing lacking in BMW's Norwegian map data: Usually the eco mode tells you about upcoming roundabouts, speed limit drops, and other reasons to slow down at the exact time you need to lift off to freewheel down in time... except it doesn't in Norway
All is still well. Discovered the most useless but awesome feature lately: The fuel tank fill state in the app updates itself at about 2Hz while filling up I'll eventually try to make a video when I have a second camera with me.
