After about 4 years of flawless performance, my Ford Fusion navigation is getting lost. The arrow of where I am deviates from the road by several blocks to the right or left of my actual path and usually or one or so blocks behind my actual location. If the navigation system is trying to give me directions to a known location, the system tries to get me back on the correct road -- the one I am actually on. This makes for very confusing directions that must be ignored.
What can be done? Some time ago I had an electronics problem and the Service department told me to disconnect the battery for about 15 minutes and then reconnect it. That fixed the system then; should I try the same now?
