Jaaaaaaaaaag

Thanks for the replies people, I've had a busy couple of weeks so I've only just had it back out to check and it was the fibre optic plug had come apart inside so all fixed! 

The soloution I came up with for the freeview was a car tuner and aerial for £40 (xtrons) and an RF modulator second hand for £10, it was a bit of a nightmare to wire up as there's four aerials into the car t.v. but it works well with good picture quality. If anyone wants more details just send me a message

Hi everyone, I've just converted to digital t.v. in the car for a fraction of the cost that any companies can offer (£50!) and it works a treat however I now have no sound/cd changer/phone module/voice control. I'm pressuming it's a D2B problem with the fibre optics, I have tried running the test procedure and neither combination of buttons do anything (fm/am + eject) also there is no light coming out from the fibre optic output on the back of the stereo. 

Anyone have any idea what I can check next?
