timp4411,

I am sure that somekind of editor is existing for editing symbols for todays Garmin maps. I remember that some years ago there was discussion about Garmin map editors when Geocachers started to use maps with their GPSr. In that time for example Garmin GPSMAP 60 had only 56Mb for map storage and one way to stuff more map areas into that memory was to reduce unneccessary symbols from maps.
