2) At the start of a journey the car uses it's hardcoded speeds for each type of road TO DETERMINE "THE QUICKEST ROUTE". If you were able to change these values then the Navgation system would potentially choose a different route based on the new rules that are set.
For example, in the UK, the A1 is really more like a motorway than an A road (in terms of average speeds), BUT I have no way of telling Nav that my A Road speeds are generally higher than the presets.
SO, as a consequence, the Nav calculates relatively few routes using the A1 (and other fast A roads I use).

Welcome back, browellm!That's exactly the point (#2)!
Also it would give us a better ETA at the beginning of the trip, but the route calculation (what route, which roads are going to be used) is what would make a big difference. So that's the main reason, as you said. And if other manufacturers can do it, BMW's should be able to do so too.
I got dizzy by explaining it again and again.

I just got the confirmation, that all my requests (I had a whole bunch of 'em) have been forwarded to the tech guys who are now thinking about it and maybe will sent a reply soon.
