Any one give me any pointers as to why I can't open the sub-menus in the instrument cluster display other than its completely bust. Just got round to changing the time. Usually do it through COMAND but didn't work this time. Tried using the buttons on the cluster and wheel but although I can get to the settings sub-menu I can't open it. Everything else works but not this. Hasn't bothered me since the clocks changed but now I can't correct the time its really irritating.
