GF82.60-P-3118CAJ Component Description For Digital TV Tuner
- with CODE (527) COMAND APS with single DVD drive (with navigation system)
- with CODE (498) Japan version

Component Identification:

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

Task
The digital TV tuner has 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 for MOST via a direct line
- TV 1 and DAB band III 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 (A2/54) (model 207.4) over a coaxial cable

MOST
The TV digital tuner is a subscriber of the MOST, via which it communicates with the COMAND 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 and DAB Band III antenna amplifiers
- TV 2 and KEYLESS-GO antenna amplifier
- TV 3 antenna amplifier (model 207.3) or TV 3, FM2 and DAB band III antenna amplifier (model 207.4)
- 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 digital tuner 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).
