TV mode, general
With CODE 865 (TV tuner), the tuner unit makes it possible to receive digital TV channels. The tuner unit separates the video and the audio signals from each other and forwards them separately. The TV mode is therefore comprised as follows:
Operation function sequence
Function sequence for TV signal reception
Function sequence for video signal
Function sequence for audio signal
Additional information (except CODE 498 (Japan version))
Additional information (with CODE 498 (Japan version))
The COMAND controller unit switches the TV picture off when the vehicle starts to move. When the vehicle is moving, only acoustic playback remains active and - for safety reasons - a warning is shown on the Audio/COMAND display. The COMAND controller unit receives the speed signal via interior CAN from the instrument cluster.
