There is a simple import process that reads “Garmin (csv)” files on the form: 13.27141, 55.53639, "K108N01@80" 13.25691, 55.55859, "K108N02@80" ….Many “GPS data files” (POI databases) are available for free download on the internet. To import data simply put your downloaded data file on the sd-card – named “speedcams.csv”.For further instructions see: http://www.matjosoft.se/android/speedcam-import.htmlImportant notice:1) This app and its author does not encourage driving above the speed limit.2) Since the functionality is dependent on a POI database of your choice this app makes no guarantee about the correctness of the warning function.
