The maps on Autoroute (should have the same map as Mappoint) cover the whole norway but not very detailed, alot of side roads are missing.
I have used "route 66" to navigate around oslo. This seems to be good with street level but only covers oslo.
So I end up using both...not axactly ideal but I had no choice.
TomTom should be detailed in main europe...I remember having 8 CD just for the maps. Mappoint uses 2 CD for the whole world
