I have a marea 1.9TD after changing the cambelt the radio died, checked the fuses, all ok, pulled the radio and metered the inputs, one 12v all time, one switched with ignition, one eart and a couple that did nothing, this seemed to agree with sticker on unit. Took radio to ice specialist and they pluged it in to their display counter and it was ok, coming up with the code screen, back in car no go, or sometimes a couple of dots. Any ideas????

Put a redirect in ICE section for you.
