Before you begin
Traffic information (TMC)
The navigation device has an integrated TMC receiver. As soon as it is
mounted, the device can receive traffic message updates. If required, it
can change your route dynamically, e.g. in order to avoid a traffic jam.
2.4.3
Memory card
A memory card is not required to operate the navigation system
because all the data needed for navigation are stored in the internal
memory of the device.
Note:
If you purchase additional navigation maps, they must be saved
in the internal memory of the navigation device. Navigation data on the
memory card are not used. The slot for memory cards is intended only
for media which you can play back with the media player or the picture
viewer.
When you connect the navigation system to your computer using a USB
cable, the internal memory is detected as the 'NAVIGON' drive. The slot
for the memory card is detected as the 'NAVIGON SD' drive.
Data backups, software updates and navigation map updates can be
carried out quickly and conveniently with the
NAVIGON Fresh
software,
which you can download free of charge from the website
www.navigon.com/fresh
.
Caution!
Do not remove the memory card from the device while the
data saved on it are in the process of being used, e.g. for playing back
music or viewing pictures. Data may be lost as the result.
Note:
A change of memory card is detected only when the device has
been switched on. If the memory card is not detected, insert it again
when the device is on and running.

Navigating with GPS
GPS is based on a total of at least 24 satellites orbiting the Earth and
continuously transmitting signals of their position and time. The GPS
receiver receives this data and calculates its own geographical position
on the basis of the information transmitted by the various satellites.
Data from at least three satellites is required for positioning with an
acceptable degree of accuracy. With data from four or more satellites it
is possible in addition to determine the position's altitude above sea
level. Positioning is accurate to within three metres.
Once the navigation device has determined your position, this position
can be used as a starting point for calculating a route.
