2.1 Software Installation

1. Insert the memory card into your device.

Note: The memory card must remain in the device during

operation of the navigation system.

2. Slide the main switch on the under side of the device to

the ON position.

The installation will now be carried out.

2.2 Navigation with GPS

GPS is based on a total of 24 satellites that circle the earth

and, in doing so, are constantly transmitting their position and

the current time. The GPS receiver receives this data and

calculates its own geographical position on the basis of the

information broadcast by the various satellites.

For a sufficiently precise positioning it is necessary to obtain

the data from at least three satellites. With the data from 4 or

more satellites the altitude above sea level can also be

ascertained. The determination has an accuracy of about 3

yards.

Once

MobileNavigator 6 has determined your position, this

position can be used as a starting point for a route calculation.

The map data on your navigation device includes the

geographical coordinates of all digitally recorded points of

interest, streets and places. From this the server can calculate

a route from any given starting point to a destination.

The calculation of the current position and its representation

on the map takes place once every second. So your current

position is always shown on the map.
