Just speaking on behalf of Nigel - who I hope won't mind - if your radio has the 4 holes on the facia then you can get away with pushing in stiff wire (cannibalised coat hanger maybe) or even thin screwdrivers. Just don't poke them in too far (an inch will do) and very gently press them outwards, pulling at the same time.
Does this serve you right, when the rest of us are in wet freezing Britain????? :) Cheers and enjoy hol!
