system displays the message “Are you sure you want to delete this address?” Click “Yes” to
delete the saved address.
•
In Navigation mode, POIs are displayed in real time. The icons showing the position of the POIs
are thus displayed on the map and move with it. If you select a lot of POI categories to display or
if you clicked “Select All”, the information on the screen may update more slowly.
•
The total calculated distance and time for the journey are given at the beginning of the
driving directions.
•
By clicking the up and down arrows, you can scroll through the driving directions. The
map display is then automatically centred on the change of direction given by the driving
directions.
•
If the GPS position is outside the limits of the map installed in the system, the GPS cross
may appear in the middle of a blank screen. By zooming out, you can then locate the GPS
position in relation to the maps installed in the system.
•
When “Centre on GPS position” is selected, the “Location Marker Option” function is no longer
enabled. You need to move the location marker to be able to access the function again.
•
The position established by the GPS can be affected by several factors:
- the reception quality of the American satellite signals;
- the surroundings (buildings, tunnel, high-voltage cables, etc.);
- the battery power levels in you ViaMichelin Navigation X-980T,
- the accuracy of the GPS position calculation (± 15 m);
- etc.
•
To prolong battery life, we advise you to leave your ViaMichelin Navigation X-980T system
connected to a power source or to recharge it after use.
•
The ViaMichelin Navigation X-980T also has an “ Avoid ” function which automatically
recalculates a new route in order to bypass an accident, roadworks, etc. You access this
function by clicking on the Navigation screen then “
Bypass Route ”, and specifying the
distance you want. This function is only enabled in Navigation mode when the GPS has
been activated.
•
“Recommended” route calculations are designed to optimise comfort and safety while
offering a good compromise between time and distance.
•
The “Shortest” routes take the roads in the database that are closest to the straight line
between the departure point and the arrival point.
•
The “Quickest” routes take the roads that give you a shorter driving time than the
“Shortest” route. In Navigation mode, the software only uses this type of calculation.
Moreover, during short journeys, the software uses the table of average speed settings for
the 6 types of roads programmed in the map database when calculating the “Quickest”
route. Therefore, you can favour some types of road by reducing the average speeds of
others or by increasing the speed of the type to favour. However, for longer journeys (> 100
km approximately), the programme calculates the route based on the primary network
(motorways and similar roads); the secondary network is only used to get from the
departure point to the primary road and from the primary network to the arrival point.
•
In Free Navigation, only 2D display is available.
•
When there are several stages in a route, you can click “Go to Next Stage” to tell the system
to recalculate a new route between the GPS position and the next stage. This means you
