I have just bought a 2004 TD6 Vogue with CD Sat Nav. Unfortunately the radio/TV/Sat Nav does not work, the power light on the LHS of the screen illuminates and the screen lightens slightly but there is no sound or vision. A dealer has said there is water ingress and all three units in the nearside rear have to be replaced at £1125. I have removed and opened all three units and there seems no sign of water in any of them but there is signs of water on the cases and in the connectors. The connectors seem to be covers in blue grease, which I will try to clean up.

I cannot believe that all three units are suddenly damaged at once, how can I test where the real fault is? Which unit does what?

Thanks Chris

Did you undo the cables that go into the box on the right of the pic? One is not plugged in and the other not locked in position!

Yes, I had started to take them out when I took the picture.
