Can anyone please tell me how to remove the radio from a UK spec E39 5 series? I thought that there was a torx screw behind the volume switch, and although this has been confirmed by contacts on the US Message Board, I still can't see the screw or how to release the radio from its location......I need to get the radio out to fix the cassette door, which isn't staying down anymore - I've been told that there is a little damper/oil pot that is probably broken and needs replacing - doea anuyone have any ideas where I can get one of these?

Any help with any of this would be really helpful. Thanks
