Caution!
Be sure to refer to all the safety information in chapter
"Important safety information" on page 9.
Note:
Insert the USB connector securely in the corresponding USB
sockets!
Note:
It takes approx. 3 hours to charge the device when the battery is
flat.
A fully charged battery enables up to 3 hours of use depending on the
device configuration.
TMC antenna
The navigation device has an integrated TMC receiver. The TMC
antenna is integrated in the car charger cable. Once the car charger
cable is connected, the device can receive current traffic messages. If
required, it can change your route dynamically, e.g. in order to avoid a
traffic jam.
2.4.2
Memory card
A memory card is not required to operate the navigation system
because all the data required for navigation are stored in the internal
memory of the device.
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 back-ups, 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
.
If you purchase additional navigation maps but no longer have enough
space for them in the internal memory of your navigation device, it is
also possible for you to save these maps on a memory card microSD
which you then insert in the device. The navigation system can use
navigation maps from both memories.

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.
