DESCRIPTION AND OPERATION
Software Loading
The system is capable of having operating software
loaded via the CD-ROM drive. This allows for different
languages to be loaded and also allows systems to be
updated when new software/features are available.
The Navigation computer is delivered pre-loaded with
operating software, 2 default languages and the Off
Road navigation software. The 2 pre-loaded
languages are:-
•
UK English (Female)
•
German (Male)
Software loading can be achieved at any time by
inserting Software CD into the CD-ROM drive. The
navigation computer compares of the version of
software on the CD with that currently loaded. If the
software version on CD is a later version it
automatically starts to load the software. The status of
software loading is displayed on the display and
control unit’s screen. On completion of software
loading, the CD is automatically ejected. The user is
prompted to remove the CD and confirm. The
computer then resets and restarts with the new
software.
Language loading is also achieved by inserting the
software CD (as this also contains all the navigation
languages). By selecting a language to load, then
selecting a language to delete in its place the
replacement language is loaded with a status screen
to accompany it. On completion of language loading,
the CD is automatically ejected from the navigation
computer. The computer then resets and restarts with
the new language loaded. This needs to be selected
from the settings menu.
Diagnostics Mode
The navigation system may be put into a on-board
diagnostics mode (service mode) by selecting the
’settings’ menu from the main menu then pushing and
holding the menu key for about 10 seconds. The
service mode has four main functions:
1. To check that components are fitted and to
determine their hardware/software levels.
2. To perform a quick ’health check’ of the major
input signals to the system.
3. To check for correct operation of the Display and
Control unit keys.
4. To check the status of the GPS reception.
Selecting the On-Board Monitor item from the service
mode menu causes the version info to be displayed.
The screen displays the software and hardware level
of the display and control unit together with the
diagnostics and bus index. The supplier of the unit is
also displayed as a number code defined by BMW.
The system queries the display and control unit before
displaying the information on the screen. If the unit
responds with Software Hardware levels this implies
that the component is connecting to at least Power,
Ground and K-bus.
