GF82.60-P-3106CA Component Description For TV Tuner (Analog/Digital)
- with CODE (863) Digital/analog TV tuner

Component Identification:

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

Task
The TV tuner (analog/digital) performs the following tasks:
^ Receive signals
^ Demodulating and decoding signals
^ Transmitting signals

Receive signals
The input factors are read in via the following connections:
^ Direct lines
^ Media Oriented System Transport (MOST)

Direct lines
- Electronic wake-up via a direct line
- TV 1 antenna amplifier (A94/1) via a coaxial cable
- TV 2 and KEYLESS-GO antenna amplifier (A94/2) via a coaxial cable
- TV 3 antenna amplifier (A94/3) (model 207.3) or TV 3 antenna amplifier, FM2 and DAB band III (A2/55) (model 207.4) over a coaxial cable

MOST
The TV tuner (analog/digital) is a subscriber of the MOST, via which it communicates with the COMAND operating, display and controller unit (A40/3).

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

Transmitting signals
The signals are transmitted via the following connections:
^ Direct line
^ MOST

Direct line
- Phantom power supply to following antenna amplifiers:
- TV 1 antenna amplifier
- TV 2 and KEYLESS-GO antenna amplifier
- TV 3 antenna amplifier (model 207.3) or TV 3 antenna amplifier, FM2 and DAB band III (model 207.4) over a coaxial cable
- Transmission of video signals (Y-brightness (luminance)/C-color information (chrominance) (Y/C)) via Y/C lines to the COMAND controller unit

MOST
The TV tuner (analog/digital) is a subscriber of the MOST, via which it communicates with the COMAND controller unit. The audio signals are transmitted to the COMAND controller unit or the sound system amplifier control unit (N40/3) (with code (810) Sound system).
