Route calculation and visual guidance
Symptom Possible 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.
[Calculate] must be selected for route calculation after Waypoints are
selected from the “Edit/Add to Route” screen. Touch [Calculate] after selecting waypoints.
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.

A part of the route is not displayed. The suggested route includes narrow streets (roads displayed in gray). This is not a malfunction.
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.
