RADIO Not Working Blank

[paulant18]

All this is frying my brain. On my 2005 S40 I have one optical cable going into the infotainment module and that's it!! No other cable, other than main and speaker block and no optic for the radio! There's no amp that I can find, try work this out for me!! the

Hi
I have this same fault on my 2005 T6 XC90. Press on/off once, nothing. Press it again display lights up for 3 seconds then goes out. Balance etc adjustable, but no sound comes out.
Has anyone defined what is the fix? I have had mouse issues in the car, but don’t want you to be influenced by this UNLESS it could be the reason.

God, these cars are stupidly complicated. I already have the rear rear diff control system failure, “Anti skid service required”, so the car is not saleable. I would just like to have a sound system while running it into the ground and then scrapping it. It runs on LPG, so that puts the EM light on thanks to it being too clean for the lambda sensors.....and makes it an MOT fail for being too environmentally friendly.

My other car is a 1990s TVR. Old tech, easy to fix. Simple, and far more reliable than the Swede, which frankly is more of a turnip......

It is a MOST fiber ring.
All the video and audio channels travel around the ring on the fiber
That's how they work
