Your navigation system will use a low amount of electricity and
the batteries will be discharged, even when it has been turned off.
It is possible for the battery to loose so much energy that an ini-
tial installation will be necessary once again, if you do not use the
navigation system for a longer period.
III. Installing the Navigation Software
The final installation of the navigation software will take place
automatically from the internal memory, during the initial setting
up, if your device has already been equipped with the basic data
of the navigation software at the factory. Follow the instructions
on the screen.
An optional memory card will always have to be inserted in the
device during the use of the navigation system, if it contains
digitalized map material.
It will be necessary to carry out a Reset to restart the navigation
system if the memory card has been removed, only for a short
time, while the system was being used (see page 24).
Please also read the chapter Navigation starting on page 25.
