How a Route Is Set
•
In some cases, the set route may assume travel in the opposite direction to your current
heading.
•
In some cases, a route may begin on the opposite side of a railway or river from your actual
current location. If this happens, try setting the route when closer to where you want to travel.
•
Sometimes a route will unavoidably be set along roads in an area set to be avoided.
•
It is possible that guidance may direct you off a motorway and then back on again.
•
In some cases, guidance may direct you past your destination and then indicate a U-turn to
get back to it.
•
If a route along a normal motorway passes near a motorway service area, the system may
mistake the service area for a motorway junction.
•
If a suitable route cannot be set in compliance with the specified “DETOUR” parameter, an
area to be avoided, or your preference to avoid motorways, the setting or parameter may be
ignored.
•
If your destination is a motorway junction, voice guidance may not announce the junction.
•
There may be instances when the starting point and the destination point are not on the
highlighted route.
•
When performing a “RESUME ORIGINAL ROUTE”, the shortest way back to the original
route is found. It may take you along winding roads, narrow city streets, and other non-
optimal roads.
Route Highlighting
Once set, the route is highlighted in bright green on the map (except in Arrow mode).
•
On major motorways and wide roads, where a road is on multiple levels, or in mountainous
areas with many hills and curves, the highlighted route may not coincide exactly with the
map.
•
The immediate vicinity of your starting point and destination may not be highlighted, and
neither will areas with particularly complex road layouts. Consequently, the route may
appear to be cut off on the display, but voice guidance will continue.
•
If you set a further destination, the route to the second destination only becomes highlighted
after you reach your first destination.
