Hello I really need help here, I was taking a look at my friend's new cx9 when I accidentally pressed the menu button followed by couple of touches like next , agree, proceed .. and then I found myself stuck in a window that I can't get rid of saying please enter the MAP DVD. If I press fm/am for example, it switches to fm but the screen won't show the main screen of fm ( like the fav and stuff ) .. non of the buttons switched it, except eject button but when I press fm/am it switches back to this MAP DVD window.. I'm really embarrassed guys please any help would be much appreciated.
