It does come out fairly easily, but I bought a cheap set of plastic removal tools which made it even easier. Look around the panel to the right of the steering column (On R Hand drive cars) and you should find sufficient gaps to get a tool under and pull straight. Once the panel starts to lift, you can then move the tool to different positions, pulling a little at a time until it frees off. If you're careful, it should come off with no marks and all the retaining clips intact. Once the panel is off, you'll see where the radio retaining brackets are screwed to the dash frame, remove these and ease out the radio. Replacement is the reverse of removal, pushing the dash panel squarely back in with the palms of your hands. I replaced my radio with the DAB version, hence my reason for dash removal. Be aware that if you replace your radio, then you'll need to get a reset carried out.(Total mileage recorder will be flashing all the time).
