We have a 2007 X3 and the screen on the flip-up display is frozen up, meaning we can't get into nav, the radio will not turn on and we can't change the time. When using the knob to scroll through the menus, there is no response. Is there a way to re-boot the computer on this model? I did a search and could not find a procedure. Any ideas? Has anyone else had this problem?
