Information & Entertainment System - Functional Description: Headunit: Notes

As headunits, control units from different system suppliers can be used.

Example:

• High version Car Information Computer (CIC)
• Basic Version Car Information Computer (CIC)
• 2nd generation Central Headunit and Multimedia Platform (CHAMP)
• Head unit basic version (HU-B)

The basic version of the CIC, the 2nd generation CHAMP and the basic head unit are identical in function  .

The differences compared to the High Version of the CIC are:

• No entertainment server
• Navigation system with fewer functions or no navigation system
• No hard disk, so with memory card

The following section describes the High Version of the Car Information Computer (CIC).

The Car Information Computer is the headunit in the MOST network.

The essential new features  for the CIC are:

• Extended functions for existing systems, e.g. navigation (see also Owner's Handbook)
• Additional functions, e.g. central database for address data
• Additional hardware, e.g. hard disk (80 GB) or USB port
• Changed hardware e.g.:
  • LVDS data line to the Central Information Display (CID) as two-wire connection
  • 1 Drive for DVD and CD
  • Control panel for audio, including favorite buttons, one unit with control panel for IHKA
• Changed display and operating concept for control center via:
  • New layout of the user interface on the CID
  • New controller with 7 fixed selector keys
• Reduction of the virtual control units in the CIC

Changes to the software and hardware have made it necessary to extend the diagnosis for the Car Information Computer accordingly.
