I have added points to the 25 mph hour file. It enters immediately, however it does not appear in the "USA safety cameras" (at least immediately).
I'm just wanting to make sure someone actually merges these from time to time or whether we are really making totally separate data files that all need to be uploaded onto the GPS.
Looking at the data in the all-in-one file vs the data in individual speed files (e.g. 30 mph file) and they are in complete disagreement. what's in one is not in the other and vice versa. the all-in-one file description warns not to combine with any other files for fear of duplicate warnings, but it looks like that file is very incomplete. i'd rather get 2 warnings than none...
