ESP LINCOLN BLACKWOOD 2002 Navigation Manual

When starting up, the navigation system may tell you: ªYou are leaving
the digitized areaº. The displayed map will then show the vehicle
position off the road. If there are other roads in this area, the navigation
system may send inappropriate messages. This means that the system
assumes the vehicle is on one of the other roads.
²When the vehicle has been parked for a long period of time, the
navigation function may be temporarily unresponsive. The
navigation system will operate reliably again once GPS
reception is available for a few minutes.
Limited GPS reception
System performance may be adversely affected if GPS reception is
interrupted or interference occurs over a distance of several miles. The
following are possible causes for GPS reception being interrupted. If the
vehicle is:
²in multi-story parking garages,
²in tunnels and under bridges,
²in between high buildings,
²by forests or tree-lined avenues,
²in heavy rain showers and thunderstorms,
²in valleys and in mountainous regions.
The digital road map
In order to plan a route, the current car position, destination location, as
well as all the roads in between are needed. This information is available
on digital road map CDs which you insert into your navigation computer.
Real road network
Introduction

Line pattern of the digital map
On the map CD, the road network is stored as a line pattern, which
means that even extensive junctions only have one center point all roads
lead to. That is why the navigation system indicates the distance to the
next turn as the distance to the center of the junction. Therefore, the
distance indications for freeway exits given by the navigation system may
be different from those on the freeway signs. The freeway signs refer to
the distance to the beginning of the exit.
Latest map CDs
Approximately 10±15% of the traffic network is changing annually. Due
to these constantly changing conditions (new roads, traffic restrictions,
etc.) a 100% correspondence of the digital road map with reality cannot
be achieved under all circumstances. We recommend to always use the
latest version of the map CD for Navigation.
Updated CDs are available twice per year through Navigation
Technologies. Refer to theOrdering additional map CDssection in the
Map CDchapter for more information.

²Select an intersection displayed
in the list.
Guidance is not precise. An inaccuracy of 30 m (100 ft) is
within the limit.
Displayed vehicle position by the
navigation system does not
correspond with actual vehicle
position.Bad GPS reception for a longer
period of time.
²If necessary, wait a few minutes.
The system automatically corrects
the position as soon as sufficient
GPS reception is resumed.
Guidance advice does not
correspond with actual traffic
situation.It is possible that the vehicle
position calculated by the system
is currently wrong. The roads may
be changed and do not correspond
with the information stored on the
map CD.
