my c5 sat for a week. i just started it up and immediately notice that the heads up display had lowered itself somehow. i keep it all the way up so i can see it. it is barely visible now. it will go down even more, and slightly sideways, but not any higher up on the glass...it looks like the mechanism is working in there, going all the way from top to bottom on its little track....anybody know if this is an easy fix, perhaps a "do-it-yourselfer"?
