General notes

When working on the CIC, particular attention must be paid to electrostatic discharge (ESD). When working on electronic components of the CIC, comply with the following rules:

• The work must be performed on a conductive and earthed workbench. The additional special tool 12 7 192 is also used.
• The earthing cable is to be connected to a safe earthing point (water pipe, heating pipe, power socket earthing).
• First of all, the person doing the work puts on the wrist collar to achieve a discharge before taking parts out of the packaging.
• The electronic components are placed on the antistatic mat and also connected to the earthing cable.

On the Car Information Computer (CIC), fewer components can be replaced that on the Car Communication Computer (CCC). The following components can be replaced:

• Complete CIC
• Complete operating facility for IHKA and audio

The "Options" sub-menu provides the possibility to back up the complete music collection. Here, the data must be stored on a USB stick. Use a USB stick with a storage capacity of 8 GB. This function is already displayed in 03/2008, but is only enabled from 09/2008 onwards.

A data backup is only possible if the hard disk of the CIC has not been damaged and the interfaces to the CIC are still working perfectly. No recovery of music data has been agreed with the manufacturer of the CIC (Harman/Becker). This means that without a data backup the music files are irrevocably lost.
