BMW 7 Series: Principals Of Operation

Comparison of CIC with CCC

The ASK system was installed in E65/E66. With the E60, ASK developed into M-ASK and the further developed CCC which was available as an option.

The multi-audio system controller M-ASK is the central control unit of the information and communications systems. The M-ASK combines up to four control units in one.

The M-ASK combines the following control units in one housing:

• ASK
• Antennal amplifier/tuner
• MOST CAN gateway, interface to control display

In the E65, these modules were separate control units.

The car communication computer CCC is the central control unit which combines the functions of the M-ASK, plus some additional functions.

Voice control of the systems and the navigation system with map presentation were made possible with the CCC.

The CCC also contains the driver for the rear passenger compartment display.

The CCC performs all the functions of the M-ASK as well as offering Navigation and additional programming possibilities.

As part of this development from the ASK to the CCC system, the radio tuner, navigation, voice recognition and actuation as well as video signal processing were integrated in the CCC.

A comparison is repeatedly made in this training information between the predecessor, Car Communication Computer head unit and the new CIC head unit.

The following table shows a comparison between the previous menu items of the CCC (bold print) and the menu items of the CIC (bold print).

CCC AND CIC MENU COMPARISON CHART

The star-shaped operating concept of "Turn-Press-Push" of the CCC has been further developed in the CIC.

The sub-menus in the main menu now are arranged in lists.

All listed sub-menus can be accessed in the start menu by "turning" and "pressing" the controller.

Several sub-menus can now also be selected by means of the direct access buttons on the controller.

The windows of the selected submenus are placed horizontally one over the other.

Display

The display used for the Car Information Computer is the same CID (Central Information Display) known from the CCC.

In the F01/F02, the screen size has increased to a diagonal of 10.2" (26cm).

The number of pixels has doubled in the CID from 640x240 pixels for the CCC display to 1280x480 pixels in the CIC central display.

The new display delivers a crisp and improved picture quality compared to the previous system.

The graphic layout of the user interface has been totally redesigned.

The rear view of the F01/F02 control display is shown in the following with the two connections.

Controller

The second most important hardware component of the BMW iDrive system is the controller.

The new controller has been completely redesigned compared to the CCC controller.

The most noticeable new feature of the CIC controller are the seven direct access buttons.

It is now possible to access the following menus directly:

• Main menu
• CD/Multimedia
• Radio
• Navigation
• Telephone

The following menus can still only be selected from the main menu, i.e. with no direct access:

• Contacts
• BMW Services
• Vehicle information
• Settings

The "Back" button is pressed to go back to the last display view. Up to 30 "back" steps are possible with this button.

The option button makes it possible to make fine adjustments or carry out special functions in the sub-menu last selected.

The direct access buttons replace the "long push" function. With this function is was possible to change from a sub-menu directly to another sub-menu in the CCC by pushing the controller in the corresponding direction for at least two seconds.

The respective sub-menus are now selected directly by pressing the CD/multimedia, radio, navigation or telephone buttons twice.
