In the automatic reroute calculation, the waypoint is not
included.

matic reroute calculation.

add it back to the route.
Route information is not displayed. Route calculation has not yet been performed. Set the destination and perform route calculation.
The vehicle is not on the suggested route. Drive on the suggested route.
Route guidance is cancelled. Turn on route guidance.
The automatic reroute calculation (or detour calculation)
suggests the same route as the one previously
suggested.
Route calculations took priority conditions into consideration, but
the same route was calculated.
This is not a malfunction.
The suggested route is not displayed. Roads near the destination cannot be calculated. Reset the destination to a main or ordinary road, and
recalculate the route.
The starting point and destination are too close. Set a more distant destination.
The starting point and destination are too far away. Divide the trip by selecting one or two intermediate
destinations, and perform route calculations multiple
times.
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.
The landmark information does not correspond to the
actual information.
This may be caused by insufficient or incorrect data on the map
SD-card.
Updated information will be included in the next ver-
sion of the map SD-card.
The suggested route does not exactly connect to the
starting point or destination.
There is no data for route calculation closer to these locations. Set the starting point and destination on a main road,
and perform route calculation.
