Yes checked all discs are the right way up. Checked the cartridge is the right way round. Ive wobbled it as it searches . Ive unplugged it and re plugged it but still no joy. By the way would it still check to see if it had CD's if it was not plugged into the head properly? I wanted to check I wasn't being completely dumbo before I took the whole thing back to the dealers who sold the car as I have this fear they would just press a button with a smug smile and say 'there you go' as it burst into life !!!! But if you guys cannot assist I may have to - either that or get an ebay deal. Incidentally thanks for the damp idea - not thought of that - but its as dry as a Methodists Tea Party :)
