Software Update, Camera Guides Gone, Can't Select Views

Software updated last week (over the air, got in and it asked to update, I said go ahead). Next day, the guidlines on the cameras are gone, and I cannot select a different camera view. The buttons are there, but grayed out. forward camera comes on if I hit the view biutton in drive, and the backup camera comes on in reverse. The bed-view camera does not come on at all. Review camera appears to be unaffected. Anyone else have the issue or a fix?
