Hi

currently have a 2003 turbo with Bose and most

installed the pccm no sound

pulled the fibre optic at the CD player to check and no red light shining through cable

this point think I have messed fibre cable

so pull out pccm and pop pcm back in

works straight away

check fibre optics at cd changer again and red light

back to the head units - on pcm the fibre optic light in on in a constant state

when I plug the pccm back up the fibre optic light from the control unit is cycling

one second on about 30 seconds off when it is on for that one second I get sound

What have I done wrong?

the fact that it is regularly cycling makes me think it is something I have done or not done or is the control unit faulty?

any suggestions please?

many thanks
