start from the centre arm rest/cubby hole inbetween the seats. Open the lid and there should be two plastic nipple type screw covers. Prise these off and there are two screws underneath.
Unscrew them. Then pull the plastic cover up and forward and this will remove the handbrake surround.
Next pull the gear lever surround out, again up and forward - it shouldnt be screwed in.
Next the stereo surround. remove the ashtray. The surround is only pressed in, however check there is no screw holding it in underneath the ashtray.
Now gently but firmly pull the bottom backward and upwards, there are four clips holding it in place.
Once thats off you'll see the screws to remove the stereo.
Theres a pic with these bits removed on this page:
