Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
System Integration
The voice control system is loaded as pure software in the car communication computer. The voice control system makes use of the memories and processors in the car communication computers as well as the hardware of other systems (e.g. microphones).
The two hands-free microphones in the front roof console are used in connection with the voice control system. The hands-free microphones are connected directly to the telematics control unit (TCU). The TCU sends the microphone signals via MOST to the car communication computer where they are processed in the DSP in order to execute the required functions.
