I'm reposting this from a semi-related topic, but thought there would be more exposure here on it's own. The other day I took a trip, put my X in the car dock, and set Nav to my destination. About an hour into my trip, Nav would intermittently close, and would return to the home screen. However, the app wasn't always completely FC'd, but running in the background, and could be returned to by dragging down the Notification bar and reselecting it. This continued for the last 2 hours of my trip and was extremely annoying. Has anyone else experienced this? Is there a solution?
