There are 5 screws securing the odometer trim above the speedo cluster. The rest of the panels are clipped in I think (been a while since I've had them off).
Once you've removed the odometer panel, flip the lid up on the storage tray to the left of the handbrake and then pull upwards to remove it.
You can then remove the panel around the gear stick (i lift at the rear, then either side of the gear stick then the front).
You should now be able to remove the radio/ac panel, then the speedo cluster panel and finally the ignition key panel.
Im pretty sure all bar the odometer panel are held in with clips alone, but best check for any obvious hidden screws.
Good Luck
