Lincoln Blackwood (2002) Navigation System [5/48] 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 the Ordering additional map CDs section in the

Map CD chapter for more information.
