The head unit on my x type when starting the car music comes on then goes off for upto 2 mins then the screen shows 'System does not have phone installed'. Recently I have had no volume from the radio of cd or multi changer. The only way I have been able to sort out is to disconnect the battery. Has anybody got any ideas how to fix

This does sound like a d2b (fibre optic) lead is either loose or faulty, start checking the connections to each module and behind the sat nav touchscreen unit.
