To test how reliable the Nokia maps 3 navigation is on my n97, I navigated to a place which I already know how to get. The software does well showing me how to get there. I now purposely missed my way, then Nokia maps get confused! Instead of telling me to go left, it tells me to go right. Even when I've reached my destination, it still doesn't tell me that I've reached my destination, it still tries to return me back to the point where I missed my way to begin with. It then highlights multiple paths in blue (i guess it highlights the original path + recalculated path). This will be a disaster if I'm actually in a position where I'll need to rely on it to get out of an unfamiliar area. This bug has a 50-60% rate of occuring.

Also, I searched for a Costco in Durham, NC which I know it exists (I shop there all the time), nokia maps gave me the closest location as in Washington DC! truly weird.

Nokia guys, please look into this. I can even pay for the voice guided navigation if this problem is fixed. Thanks!
