Navigation Fault

Every once in a while, I get the following message on my screen

Navigation Fault

Navigation is not functioning properly


This can happen on startup, or can occur after I've been driving for a while.

Various dealers have replaced some cable (sorry, don't know which), my APIM, and upgraded SYNC software. No dice.

Any other thoughts suggestions from anyone? Greatly appreciated.
