Information from the gyro and wheel rotation counter can be used for dead reckoning (i.e. to calculate the position). This happens for example when
communication with the GPS satellites is lost such as when traveling through a tunnel.
The multimedia module (MMM) receives traffic information messages (TMC) from the traffic message channel module (TMC) via the MOST network.
This information is displayed on the directly connected display screen. TMC (Traffic Message Channel) is a standardized code system for traffic
messages giving information about road repairs, traffic queues etc. The Japanese equivalent of TMC is called FM multiplex. There is no corresponding
system in the U.S.A.
The navigation function of the multimedia module (MMM) also includes voice guiding which instructs the driver how to reach the set destination.
The user can configure certain functions in the system settings. These functions are:
-
date and time
-
user settings, such as password.
The following functions are displayed on the directly connected display screen:
-
navigation.
The control module transmits all the signals required to control the display screen.
Multimedia module (MMM) uses the Windows CE operating system.
Display screen
Functions such as system settings and navigation are presented on a 6.5" display screen in the center of the dashboard. The display screen is directly
connected to the multimedia module (MMM). The control module transmits all the signals required to control the display screen.
If there is an internal fault in the screen or faults in communication with the control module, the quality of the display on the screen will deteriorate or the
screen will stop working completely. A simple way to detect a fault in the screen, or communication problems between the screen and the control
module, is to check the appearance of the image on screen.
The menu system on the display screen can be controlled either using the navigation buttons on the reverse of the steering wheel or using the screen
remote control. The infra-red receiver for the remote control is in the loudspeaker grille on the dashboard.
