downloaded POI files disappeared


I downloaded a POI CSV file into my "documents" and when I tried to retrieve it thru the Garmin POI unloader it wasn't there. What is the procedure to download a POI file then install on the Garmin 200?

File extension

Please check if file extension is .CSV and not .zip or something else. POI loader will not recognize .zip file.
