The standard filename of the MioMap speedcams file is SpeedcamUpdates.spud, found in the folder
My Flash Drive\MioMap\MioMap\POI\Speedcams on the GPS unit.
The nav software never removes outdated records from this file - it only adds extra records at the end of the file
marked Edited or Deleted which supersede previous records. These records are linked only by their coordinates.
The option 'Show superseded records in Speedcams list' on the Options sheet controls whether all records are loaded,
or only those which are currently valid. Superseded records are marked in Blue.
