The TV tuner control unit receives the following signals via direct lines:
- Power supply over circuit 31 and circuit 30T
- Electronic wake-up for MOST
- TV 1 and DAB band III antenna amplifier (A94/5), for TV-1 signals
- TV 2 and DAB band III antenna amplifier (A94/6), for TV-2 signals
- TV 3 antenna amplifier (A94/7), for TV-3 signals
Processing signals
- With code 865 (TV tuner), the TV tuner control unit decodes and demodulates the TV signals and separates them into video and audio signals.
Transmitting signals
- MOST
- Direct lines

The TV tuner control unit is a MOST participant and communicates over this with the head unit. The audio signals are transmitted to the head unit, to the sound system amplifier control unit (N40/3) (with code 810 (Sound system)) or to the advanced sound system amplifier control unit (N40/7) (with code 811 (Advanced sound system)).
Direct lines
The TV tuner control unit sends the following signals via direct line:
- Supply voltage to TV 1 and DAB band III antenna amplifier
- Supply voltage to TV 2 and DAB band III antenna amplifier
- Supply voltage to TV 3 antenna amplifier
- Video signals via a high-speed video link (HSVL) line to the head unit (with code 865 (TV tuner))
