I have been having problems with the navigation system; last December my Ford dealer had to replace the APIM Module due to the fact that the system would go black. About a week ago I was headed out of the town and the no gps sign came on my screen and there was no gps. It finally came back up showing me that I was in a completely different area. I reached my destination, turned the vehicle off and went inside. When I started the vehicle the gps came back and has been working but not accurately. When I am headed north and west the icon is going the same direction that I am but when I am heading south and east the icon is heading in opposite direction. It really plays with your brain. From what I have read there is a problem with the APIM module?
