    Broken fibre Optic Loop

    Hi Guy's,

    The result of a scan with ISTA shows I have a faulty unit in the MOST loop, I was able to use a bypass on the cd changer and the video module, both seem ok, but am unable to locate, what ISTA refers to as the CBX media module.

    Would anyone know where to find it, I have done extensive searches, but to no avail, these are the only modules in the circuit so this could be the culprit.

    This seems to be the subject everyone likes to leave alone, looks like I will have to take it to a dealer although I think it may be the CCC playing up as that's where the light is generated from, what I can work out and there doesn't appear to be any red light coming out of that.
