GF82.60-P-3106FL TV tuner (Analog/Digital), Component Description
- with CODE (863) Digital/analog TV tuner

Component Identification:

Location
The TV tuner (analog/digital) is located at the right rear of the trunk behind the panel on a bracket.

Task
^ Receive signals
^ Demodulating and decoding signals
^ Transmitting signals

Receive signals
^ Direct lines
^ Controller Area Network (data bus/CAN bus) (CAN) (with code (864) Rear entertainment system)
^ Media Oriented System Transport (MOST)

Direct lines
- Power supply via circuit 31 and circuit 30g using one direct line each
- Electronic wake-up via direct line
- TV 1 antenna amplifier (A94/1) over a coaxial line
- TV 2 antenna amplifier (A94/2) over a coaxial line
- TV 3 antenna amplifier (A94/3) over a coaxial line

CAN (with code (864) Rear entertainment system)
The TV tuner (analog/digital) is a telematics CAN (CAN A) user and it communicates with the following control units:
- Left rear display (A40/5)
- Right rear display (A40/6)
- DVD player (A40/4)

MOST
The TV tuner (analog/digital) is a MOST user and it communicates through it with the COMAND controller unit (A40/3).

Demodulating and decoding signals
The TV signals received over the antenna amplifier are internally evaluated and separated into video and audio signals.

Transmitting signals
^ Direct line
^ CAN (with code (864) Rear entertainment system)
^ MOST

Direct line
- Phantom voltage at following antenna amplifiers:
- TV 1 antenna amplifier
- TV 2 antenna amplifier
- TV 3 antenna amplifier
- Sends video signals over "Y/C" lines to the COMAND controller unit
- Sends video signals over "Y/C" lines to the DVD player (with code (864) Rear entertainment system)
- Sends audio signals over low-frequency lines to the DVD player (with code (864) Rear entertainment system)

CAN (with code (864) Rear entertainment system)
The TV tuner (analog/digital) is a telematics CAN subscriber and communicates with the following control units:
- Left rear display
- Right rear display
- DVD player

MOST
The TV tuner (analog/digital) is a MOST subscriber and it communicates through it with the COMAND controller unit. Audio signals are sent to the COMAND controller unit or the sound system amplifier control unit (N40/3) (with code (810) Sound system).
