Recently had my car sent away for some garage work. On return the system (FB980BT) seemed to work ok Connected to radio and bluetooth devices properly. But when I tried the Nav system it does not seem to be there. The App button shows the Nav option and when you press it a small igo logo comes but briefly but never actually gets to the Nav system.

Is this a sign that something has been removed or it a sign that I need to reload software - please help
