navigation update LINCOLN BLACKWOOD 2002 Navigation Manual

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.
