911 Carrera 4 (996) F6-3.6L (2004)
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.
CDR23
CDR23 Control Module
The CDR23 is installed in the vehicle with and without amplifier (internal).
The CDR23 with amplifier (internal) is used if no sound package is installed. If there is no CD changer installed on the CDR23, an optical waveguide
must be projected on the optical waveguide socket.
The CDR23 without amplifier (internal) is used if a sound package is installed.
NOTE: If there is no external amplifier (Harman or BOSE) installed on the CDR23 and if there is no CD changer installed, an optical waveguide must
be projected on the optical waveguide socket.
The CDR23 control module includes the following components:
Internal:
CDR23 GW
Internal amplifier, optional (depending on the equipment)
Tuner
Single CD
Controller Area Network (CAN) Comfort
