area.)This is not a malfunction.
An indirect route is suggested.If there are restrictions (such as one way streets)
on roads close to the starting point or destination,
the system may suggest an indirect route.Adjust the location of the starting point or
destination.
The system may suggest an indirect route because
route calculation does not take into consideration
some areas such as narrow streets (gray roads).Reset the destination to a main or ordinary
road, and recalculate the route.

correspond to the actual informa-
tion.This may caused by insufficient or incorrect data on
