Factory Radio
All you need to do is fit two feeler gauges at the sides of the stereo. At the side of the stereo there are two clips they are around half an inch from the top and bottom respectively. The top clip must be moved downwards and the bottom upwards. Just slide the feeler gauges to do this. Do one side at a time and pull it out by placing your hand in the cassette slot to pull. Do it all very gently and careful not to scratch the sides. It worked out well for me - I had to remove it to stick in the cd changer cable - good luck!
