TomTom Points of Interest (POI) files are stored in the OV2 file format. Other Global Positioning System (GPS) devices also use POI methods, though they store the data in other ways. Some GPS devices store the data, or can export the data, to Comma Separated Value (CSV) database files. CSV files store tabled or database data by separating values and figures with commas. If you have CSV files that you want to use with your TomTom GPS device, you need to first convert between the two formats.
