I have the exact same problem on my '04 sedan. When it happens, give your center console a good knock, it can sometimes alieviate the problem. I think I read about this a while ago, certain wires or part of the wireharness is wedged or pinched on some part of the frame(but this would not account for the cd only issue). When the brakes are hit the chassis flex(I figure) is pulling/tugging/pinching/whatever on those wires. I do plan to pull the centre console this summer to inspect it. I am hoping it's just the connector on the head unit, we shall see.. My other theory is the headunit itself needs repair, perhaps a loose trace or wire, bad solder point, etc.

If i have the system on radio everything works find, its only on cd mode it starts giving such problems. I have tried to switch cds but its not helping me. Anyone has any idea what could be the problem ??
