Try for example to plan a route from Via Mac Mahon, 20155 Milano, Italia to Piazzale Gabrio Piola, 20131 Milano, Italia. My N9 tells me I have to walk for 1:40h, but if you try the same on Nokia Maps website and/or on a symbian phone (I tried on my mother's Belle-powered N8) you are correctly told to take tram line 12, walk a little, and then take subway line 2.
This is just an example, no matter which route I try to plan in Milan, I always get the same result: walk for the whole distance.
I tried to plan a route in NYC, just to see if the app was totally broken, but I obtained a plausible route from Times Square to Madison Square Garden.
I don't know if it's just my N9 or if it's a more serious problem, but in any case: can something be done about this?
