Hi,
I'm trying to diagnose a fault with the car audio in my 2001 (W203) C-Class. I have Audio 10/BOSE sound system installed and have since removed a faulty CD changer from the glove compartment (I have used a connector to connect the fibres where the CD changer was located and had the CD changer removed from D2B ring via the STAR computer).
However, my sound system is not producing any sound output (this fault occured whilst I was attempting to rectify/remove the faulty cd changer) - hence I suspect that either the D2B fibre optic ring is broken somewhere or the BOSE amp is broken.
Am I correct in assuming that fibre optic signal from the head unit travels down the fibre line to the BOSE amp, through the connecter (where the CD changer was) and then back to the head unit?
I ask because, the fibre input to the connector where the CD changer was (the red end) flashes once for about 1/2 second when I turn the head unit on - I am therefore assuming that I have the correct fibre optic connectivity round the loop (ie. through the AMP) at least until the point where the CD changer was. Is anybody able to confirm that this is the correct signal and signal path before I attempt to remove the centre console to get at the back of the radio to confirm the signal is actually reaching the head unit after this point.
I am also assuming that if this is the correct signal path, then the BOSE amp is good as I have fibre optic connectivity through it. Is this a good assumption?
Greatful for your thoughts.
