The radio on my 996 C4S has no sound. It lights up OK and picks up stations but unfortunately no sound. It is the Fibre optic unit with separate amplifier in the frunk. I am trying to establish whether it is the head unit or the amplifier at fault before I send for repair. Is there any easy way of checking? One suggestion was that I should look for a red light on the output connection on the head unit
( mine is currently not showing this) but not sure if this is reliable indicator of head unit fault. Any suggestions would be greatly appreciated as I really would like to know which item need to be sent for likely (expensive!) repair. Thanks, Neil.
