CCC applications

The "Professional" navigation system has been integrated in the Car Communication Computer (CCC). There is no longer a separate navigation system. The "Professional" navigation system has the following new features:

• Map information on DVD
• Complete display of Europe and US
• Several scales 1000 km, 500 km...
• Dynamic route planning

The navigation data can be displayed on the Central Information Display (CID) on the left-hand section of the screen, or on the right in the assist window. The left-hand area of the screen has a resolution of 400x240 pixels. The secondary screen has a resolution of 240x240 pixels. Navigation data can be displayed in the following form:

• Map north-oriented
• Map orientated to direction of travel
• Arrow display
• Location

In addition to the navigation data, the following information can be displayed on the secondary screen:

• On-board trip computer
• On-board computer

The following components are integrated in the CCC for the "Professional" navigation system:

• DVD drive for reading map information
• HIP module for receiving satellite signals
• Yaw-rate sensor for precise location identification

The navigation system software is fitted in the CCC. The navigation system uses the memories and processors in the CCC. The navigation system uses the Traffic Message Channel (TMC) to detect tailbacks and traffic congestion.

If a tailback or traffic congestion is detected, an alternative route around the hindrance is computed. The system has its own diagnosis address.

GPS satellites

GPS satellites move around the earth in 6 nearly circular orbits. There are 4 GPS satellites per orbit, therefore there is a maximum number of 24 GPS satellites. Before the navigation system can process the reference signal from the GPS satellites (minimum 4 GPS satellites), the Almanac data must first be loaded.

Loading almanac data

Almanac data delivers the following data and information to the navigation system:

• UTC (Universal Time Coordinate)
• Date
• Location of the GPS satellites
• Orbits
• Operational capacity of the GPS satellites

Once the navigation system has been switched on for the first time (terminal R ON) the GPS satellite Almanac data is received and loaded. The loading time depends on the number of "visible" GPS satellites and can take up to 20 minutes during the adaptation phase. Otherwise the almanac data is permanently stored in the system.

A voice recognition system (SVS) is integrated in the CCC. The SVS can be used to operate all buttons that are displayed in the CID by means of voice commands. The advantage of this is that the driver does not have to take his/her hands off the steering wheel to change the settings during a journey. The SVS can be used to control the following systems:

• Entertainment
• Communication
• Navigation
• Air conditioning (not R56)
• Settings (R56: Setup)

There are specified voice commands that are used for the SVS. SVS engages in a dialogue with the user. If a command is not understood, prompts will be issued.

The SVS software is loaded in the CCC. SVS uses the memories and processors in the CCC. The system is activated/deactivated with the push-to-talk button on the multi-function steering wheel or with the controller (not R56).

Voice commands are input through a separate microphone that is directly connected to the CCC. This microphone is discontinued from 09/2006. Voice commands are input via the hands-free microphone.

The TV function is available as special equipment (option 601 "TV function") for the Car Communication Computer (CCC). The Central Information Display (CID) in the dashboard acts as a screen for the TV function.
