ROUTE CALCULATION AND VISUAL GUIDANCE
SymptomPossible cause Possible solution
Waypoints are not included in the
auto reroute calculation. Waypoints that have been already passed are not included in
the auto reroute calculation. To go to that waypoint again, edit the route.
Route information is not displayed. Route calculation has not yet been performed. Set the destination and perform route calcula-
tion.
The vehicle is not on the suggested route. Drive on the suggested route.
Route guidance is set to OFF. Turn on route guidance.
Route information is not provided for certain types of roads
(roads displayed in dark green). This is not a malfunction.
The auto 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.
A waypoint cannot be added. Five waypoints are already set on the route, including ones that the vehicle has already passed. A maximum of 5 waypoints can be set on the
route. To go to 6 or more waypoints, perform
route calculations multiple times as necessary.
The suggested route is not dis-
played. 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 inter- mediate destinations, and perform route calcu-
lations multiple times.
There are time restricted roads (by the day of the week, by
time) near the current vehicle location or destination. Set [Use Time Restricted Roads] to OFF.
“Route settings” (page 6-45)
A part of the route is not displayed. The suggested route includes narrow streets (roads displayed in gray). This is not a malfunction.

SymptomPossible cause Possible solution
The part of the route that the
vehicle has already passed is de-
leted. A route is managed by sections between waypoints. If the
vehicle passed the first waypoint, the section between the
starting point and the waypoint is deleted (it may not be
deleted depending on the 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.
The landmark information does
not correspond to the actual in-
formation. This may be caused by insufficient or incorrect map data. Updated information will be included in the next
version of the map data.
The suggested route does not
exactly connect to the starting
point, waypoints or destination. There is no data for route calculation closer to these locations. Set the starting point, waypoints and destina-
tion on a main road, and perform route calcula-
tion.
