Configuration
The device leaves the factory configured for
use with the coach infotainment system. The
HDMI output (HDMI out) is activated, and a
source connected to the HDMI input can be
selected. In this case, the CVBS output and the
corresponding analogue inputs (AV1, AV2) are
deactivated.
For stand-alone operation or use with another
Bosch coach system (e.g. Classic Line), the
device must be reconfigured in order to
deactivate the HDMI output and activate the
CVBS output and analogue playback via the
AV1 and AV2 inputs.
