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 calculation.
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 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.
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 5-16)
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 deleted. 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 information. 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, way-
points or destination. There is no data for route calculation closer to these locations. Set the starting point, waypoints and destination on a
main road, and perform route calculation.
