Together with the MMI, it is a fixed component of each PCM2. It provides a connection to CAN Comfort via its nodes. Diagnostic and useful data is exchanged with the CAN via these nodes. It creates links to the following systems: ♦CAN Comfort ♦Media Oriented Systems Transport (MOST), internal (electrical) ♦Voice control system (VOCS) (optional/insertion) ♦Navigation (optional/insertion) ♦Man Machine Interface (MMI) ♦Single CD ♦Media Oriented Systems Transport (MOST), external bus (opti- cal) ♦Amplifier optional (Harman or BOSE) ♦CD changer ♦Telephone/telematics 9101 Control unit function - MMI 91-75 page 15 Printed in Germany – 43, 2003 SgfMMlwl
