No speed alert on my Garmin C340


I downloaded a school file here and named it speed_20.cvs but I don't get proximity alerts and my GPS is set to give me proximity I have to add something to the file or do I have to be traveling a certain speed to get the alert?

I think that it should give you an alert as long as you are going 20mph or more. You can load the POIs manually (through POILoader) and set the speed or distance as you wish.
