No GPS Reception?
- 64 -
If there is no GPS signal, the following message appears:
You have the following options:
Wait to get into an area where there is GPS reception. Once
you enter this area, route guidance will begin.
Touch Cancel. The window you came from reappears. Repeat
your last entry later to restart navigation.
Touch OK. The system calculates the route. Therefore it
assumes the last known position to be the starting point.
The calculation terminated, the route is shown on the map,
with the last known position as starting point. This is useful if
the last known position is not far from your current position.
As soon as GPS-reception is sufficient for navigation
purposes, the system recalculates the route and displays it on
the map. Now navigation may begin.
