Had new APIM installed a few days ago..Seemed to be working until this morning..Blank screen and no radio until I made short trip and restarted the engine..Then was working again..Had schedled updates at 2:00 a.m. this morning...Any connection? Disbled my auto updates and don't plan to turn them back on unless I really need to

 

If it hasn't happened twice in a short period of time.. I wouldn't worry about it. All three of my vehicles have done it once in a while.
