Route setting information
Route search specifications
Your navigation system sets a route to your
destination by applying certain built-in rules to
the map data. This section provides some use-
ful information about how a route is set.
CAUTION
When a route is calculated, the route and voice
guidance for the route are automatically set.
Also, for day or time traffic regulations, only infor-
mation about traffic regulations applicable at the
time when the route was calculated is consid-
ered. One-way streets and street closures may
not be taken into consideration. For example, if a
street is open during the morning only, but you
arrive later, it would be against the traffic regula-
tions so you cannot drive along the set route.
When driving, please follow the actual traffic
signs. Also, the system may not know some traf-
fic regulations.
!
The calculated route is one example of the
route to your destination decided by the na-
vigation system while taking the type of
streets or traffic regulations into account. It
is not necessarily an optimum route. (In
some cases, you may not be able to set the
streets you want to take. If you need to take
a certain street, set a waypoint on that
street.)
!
If the destination is too far, there may be in-
stances where the route cannot be set. (If
you want to set a long-distance route going
across several areas, set waypoints along
the way.)
!
During voice guidance, turns and intersec-
tions from the motorway are announced.
However, if you pass intersections, turns,
and other guidance points in rapid succes-
sion, some may delay or not be announced.
!
It is possible that guidance may direct you
off a motorway and then back on again.
!
In some cases, the route may require you
to travel in the opposite direction to your
current heading. In such cases, you are in-
structed to turn around, so please turn
around safely by following the actual traffic
rules.
!
In some cases, a route may begin on the
opposite side of a railway or river from your
actual current location. If this happens,
drive towards your destination for a while,
and try route calculation again.
!
When there is a traffic jam ahead, a detour
route may not be suggested if driving
through the traffic jam would still be better
than taking the detour.
!
There may be instances when the starting
point, the waypoint and the destination
point are not on the highlighted route.
!
The number of roundabout exits displayed
on the screen may differ from the actual
number of roads.
Route highlighting
!
Once set, the route is highlighted in bright
colour on the map.
!
The immediate vicinity of your starting
point and destination may not be high-
lighted, and neither will areas with particu-
larly complex road layouts. Consequently,
the route may appear to be cut off on the
display, but voice guidance will continue.
Auto reroute function
!
If you deviate from the set route, the system
will re-calculate the route from that point
so that you remain on track to the destina-
tion.
!
This function may not work under certain
conditions.
