– If one section between waypoints cannot
be calculated, none of the route will be
displayed.
– The route may not connect completely at
some waypoints.
– The route may require a U-turn close to
some waypoints.
● Route calculation may not be completed in
the following cases:
– If there is no main road within a range of
1.5 miles (2.5 km) from the vehicle, a
message saying so will appear on the
screen. Try recalculating when the ve-
hicle is closer to a main road.
– If there is no main road within a range of
1.5 miles (2.5 km) from the destination or
waypoint, a message saying so will ap-
pear on the screen. Try setting the loca-
tion closer to a main road.
– If the vehicle is too close to the destina-
tion or if there are no roads to the
destination, a message saying so will ap-
pear on the screen.
– If it is impossible to reach the destination
or waypoints because of traffic
regulations, etc.
– If the only route to reach the destination
or waypoints is extremely complicated.
– If the destination, current vehicle position
or waypoint is within the “Avoid Area”.
– If a part of the route is included in the
“Avoid Area”.
● The following may occur when the route is
displayed:
– If you calculate a route on a main road,
the starting point of the route may not ex-
actly match the current vehicle location.
– The endpoint of the route may not exactly
match the destination.
– If you calculate a route on a main road,
the system may display a route from an-
other main road. This may be because
the position of the vehicle icon is not
accurate. In this case, park the vehicle in
a safe location and reset the vehicle icon,
or continue driving to see if the position
of the vehicle icon is automatically ad-
justed before recalculating the route.
– There are cases in which the system
shows an indirect route to reach the des-
tination or waypoints, if you set them
from stored or facility information. In or-
der to correct this, you must be careful
about the traffic direction, especially
when lanes with different travel direc-
tions are shown separately, such as in-
terchanges and service areas.
– This system makes no distinction be-
tween limited traffic control and total
control (blockage). It may show an indi-
rect route even if the road is usable.
– Even if the freeway preference is set to
OFF, a route that uses the freeway may
be suggested.
– Even if the preference is set to OFF, a
route that uses a ferry line may be
suggested.
– Ferry lines, excluding those that are only
for pedestrians, bicycles and
motorcycles, are stored in this system.
Take into consideration the travel time re-
quired and operational condition before
deciding whether to use them or not.
