If I download gpx files and choose how many feet warning notice I require then upload them with poi loader can I choose express mode and keep the settings or do I need to choose manual and put the warning distance for each file again?
I believe if you use express it defaults to whatever distance you picked when you downloaded the file. If you use manual you can put in a new distance and I believe that will override the one you chose earlier.
Have read somewhere, that the distance settings used by POI loader are calculated with the speed of the zone you are in, and you are a warning with the distance relevant to that speed, to give you enough time to react to the warning.
Used to set distances manually, but found it a waste of time as the defaults used by POI loader were good enough.
