I have a a problem with my sat nav since the battery drained, and wondered if anyone had come across this problem. I have a megane privilege with a carminat sat nav which is the mono version that works by turning the volume control etc. The unit is made by Becker. Since the battery went flat I can no longer change the clock time, or get the sat nav to find a destination, it keeps calculating the route but goes no further. I have disconnected it from the car, entered the code (4112) and still no luck. I heard on other sites that there is a setup CD, I only seem to have the Map CD, am I missing something? Not sure what to try next, hopfully one of you may know what to do.
