wiring diagram e210 dcm and stereo

[Ian Lemmy kilmister]

anyone know if the ecall speaker 
gets signal only from dcm, or the 
right speaker signal goes from the 
stereo through the dcm then to the 
right tweeter and the ecall speaker 
then on to the door speaker.

tried to make my own wiring 
diagram but have not yet dismantled
and located dcm so I have a complete
wiring diagram. will rebuild the stereo
and want to know before so I do not 
destroy the dcm module

Earlier cars had the mic and right speaker pass through the DCM, not sure on the later cars, only way to test is un plug the DCM and see what doesn't work
