Ovi Maps on N9 constantly "recalculating" until I switch lanes
 

Odd bug, when I start navigation, Ovi Maps constantly says "recalculating" over and over, moving the starting point to my current position. It only seems to stop doing this if I switch lanes. It's done it the only 2 times I tried to use navigation on a multi-laned road. When I was on a single laned road, it worked fine.

It could be that the position it gets is not very accurate, so it thinks you're on another road. I have had this issue with Tomtom devices as well. I'd say is more of a physical limitation than an actual bug, as annoying as it may be.
