Loading Custom POIs to a Device from Multiple CSV or GPX Files

More than one .csv or .gpx file containing Points of Interest (POIs) can be loaded onto the device as long as all of the files are loaded at the same time. If one .csv or .gpx file is loaded to the device and then another one is loaded using the Points of Interest (POI) Loader application, the device will overwrite the existing POIs with the current ones.  To work around this and load more than one set of POIs to your device, put all .csv and .gpx files into the same folder on your computer so that they are all loaded together. 
You can also categorize your files by having subfolders. Each subfolder can have up to 32 .csv and .gpx files. For information on adding categories to custom POIs, see null
