My 2004 is the old style and it has the next, vol, and temp buttons as well. I think @Babyburr has the old style? Or did he say otherwiseMine is 2005, so I have the redesigned button with NEXT, VOL + / - , TEMP + / - like Babyburr described. And the switch is secured down with a torx screw, so I don't think prying it off with a butter knife would work.
