PCM2 Gateway

PCM2 Control Module (Head Unit)

The PCM2 control module (head unit) includes the following components.

Internal:
PCM2 gateway.
PCM2 Man Machine Interface (MMI).
Internal amplifier (optional, depending on the equipment).
Tuner.
Single CD.
Navigation (optional/insertion).
VOCS (voice control system) (optional/insertion).
Controller Area Network (CAN) Comfort.
MOST switch.

External:
External amplifier (optional, Harman or BOSE).
CD changer (CDC), (optional).
Telephone/telematics (optional).

The PCM2 consists of at least two but a maximum of four MOST nodes, (Gateway, MMI and optional Navigation and VOCS (optional)), which communicate electronically with each other via MOST. Data is transferred outside of the PCM2 via the optical MOST.

Telephone/telematics (optional)
The telephone/telematics feature (optional) is available as an option and is linked to the PCM2 via the optical waveguide.

Tuner
The tuner is part of the PCM2 (on the main board).

External amplifier
The external amplifier (Harman or BOSE) is available as an optional feature and is linked to the PCM2 via the optical waveguide.

Internal amplifier
The internal amplifier is part of the PCM2 (installed on the main board).

Wake-up function
All control modules connected to the MOST are in sleep mode if the PCM2 is deactivated. When the PCM2 is switched on, a light is switched on via the MMI. It is reinforced and passed on by the MOST control modules that are connected.
