Take the trim off (aluminium , wood, cube etc.) starting at the passenger side of the dash, prize it off with a blunt knife and it is on pins. Then remove the bit above the radio and you will see two screws holding the radio in place.
Unfortunatley, the wires are intact, so I really don't know why the unit isnt working. It worked for 2 seconds when cornering, once, but is always silent otherwise. Odd.
