Thanks all, I managed to remove the sticker without even breaking a fingernail - nevermind damaging the new screen! As a matter of interest the sticker warned against leaving the bike in the sun as the curved screen could act as a lens which could melt the bike! Perhaps Givi got the idea from the new "Cheesegrater" building in London whose windows reflected and concentrated the sun's rays damaging several cars parked nearby. We don't suffer from excessive sunshine in N Ireland, so it shouldn't be a problem!
