Hi As I recall, this was a 3815 that was working and then stopped working.
If it's back to it's original location, then the "new" location from the survey was never saved to eprom. Once he gets a new survey, make sure to save it. If it's not saved, the unit will revert to the old location every time the power is cycled.
