Narrative:
During cruise flight the captains primary flight display (pfd)/ attitude indicator (ai) tumbled. The autopilot and auto throttles disconnected. The navigation display (nd) indicated a map fail message. The heading on the RMI changed approximately 90 degrees in wings level flight. All navigational instruments were lost. The first officer's pfd attitude was still correct; therefore controls were handed over to myself; the first officer. The captain began running through the QRH procedures. The QRH directed us to the attitude and heading fail page; which we accomplished. However; this did not result in restoring a heading. We were navigating by the whiskey compass. We then proceeded to another QRH page which allowed us to input our compass heading. Afterward; the autopilot was useful for holding basic level flight. At this time; our only navigation information was VOR directions from the RMI. We called maintenance. Our discussion with them was fruitless. Therefore; we coordinated a diversion with dispatch. Completed procedures with the flight attendants; notified the passengers; and completed appropriate checklists for the diversion. We landed safely. In this case; it appears there was a mechanical failure. Such failures happen from time to time and are not completely preventable.
