VOICE GUIDANCE
VOICE RECOGNITION
REAR VIEW MONITOR
The part of the route already
passed is deleted.A route is managed by sections between way-
points. If you 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 informa-
tion.This may caused by insufficient or incorrect data on
the DVD-ROM.This is not a malfunction.
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 desti-
nation on main road, and perform route cal-
culation. Symptom Possible cause Possible solution
