BMW 7 Series: System Components
The voice input and activation system is implemented in the following control units:
- Telematics Control Unit (TCU)
- Voice input and activation system
- CIC
The voice-input commands are transmitted via MOST or the central gateway module (ZGM) to the receiving control unit.
Voice output consists of recorded audio signals stored in the control unit for the voice input and activation system. The audio signals are then made available on the MOST bus in the form of digital signals.
TCU
The TCU used on the F01/F02 is an evolved unit based on the TCU from the E70.

The Voice Activation system supports all the menus viewable on the CID. Voice control also extends to the second level of the menu tree.
The CIC has eight languages, all saved on the internal hard disc. Three of these languages are user-selectable by iDrive. The other languages can be activated by coding.
The volume of voice output can be adjusted by means of the multifunction steering wheel and the IHKA/audio control unit.
The CIC is mounted behind the IHKA/audio control panel in the instrument panel.
Hard Disc
For the first time, a hard disc for storing applications (programs) and data is used in a head unit. It is a 2.5" hard disc with a capacity of 80GB.
0.5 GB of storage space is reserved on the hard disc for the data of the voice recognition system (iSpeech).
