Thanks for that. Now instead of walking out to my bike to go home thinking, ''Damn I forgot to look up how to change the screen brightness", I've just changed the screen brightness. I still can't actually see it when I'm riding thanks to my girly politically correct nanny state chin-bar, but while not that fond of my face I'd rather keep it than have it ground into mince because I was ogling some jogger who turned into an effeminate man when I got close enough, then look up to see I'm on the wrong side of the closed road or test-track. What am I talking about now? Anyway thanks buddy. Also to all the people telling the OP it does come with a manual, yeah it does in the UK, but that doesn't mean it does in Hungary...
