Audio fibre optic ring

[Crossing Keeper]

Hi,

I have just brought home my third S type and need some advice about the unit in the boot.  There is a phone unit, a multi CD changer and a Denso sat nav.  There is no audio from any source, CD, Radio or route guidance.  The phone button on the steering wheel merely toggles Mute on Mute off.

I don't have a phone installed and the auto changer in the boot of my previous S types was rarely used as I listen to audio books more than music. I suspect a faulty link in the fibre optic connections.

So, can I just remove the two unwanted units, auto changer and phone ?  That would match the set up in my previous S Type where the phone and auto changer plugs were just loose behind the Denso unit.

Or move the Denso unit from my old car to the new one?
