Thanks for your prompt reply. If the direction of driving is north, we may
possible not rotate the map. But if not, we may rotate the map. And the
probability of Driving north is very very small, so in most cases We need to
rotate the map! Anyone could help me? Any suggestion is highly appreciated!
thanks in advance.
Regards.
