I have a 2009 Chrysler Town and Country Limited. I took it in to have the navigation module system replaced. When I picked it up I noticed that where the compass display was suppose to show the direction on the EVIC in front of me, there were just 2 dashes. I asked them what happened and they said it must have just died and that it had nothing to do with the mechanic replacing the Nav system. I find that hard to believe. I think he hit something, which either overloaded a circuit or broke a wire. Can you offer some advice?
