This service is designed to convert GPS Favorites between different formats, used by most popular navigation software. It would definitely make a migration easier, but to be absolutely safe, you have to keep 3 very simple rules:
Favourites file is located in ".../profiles/01-04" subfolder, located on SD-Card. First - find iGo folder in the root of SD. Than locate file user.upoi with favorites:
/sdcard/iGo/save/profiles/01/user.upoi
/sdcard/iGo/save/profiles/02/user.upoi
the number could vary from in range: [01-04]
.KML files are also supported by iGO as POI files. Save your points to .KML file, give any name to it and copy to /iGO/content/userdata/poi/yourpoifile.kml
Favourites file is located in /sdcard/igo/save/favorites.dat.
.KML files are also supported by iGO as POI files. Save your points to .KML file, give any name to it and copy to /iGO/content/userdata/poi/yourpoifile.kml
Favourites file is located on SD-Card in /sdcard/Sygic/Res/db/items.db. Please do not override it without backup! If you want to keep you history ("Recent points" are stored in the same file) you have to uploaded it to GPS Favourites Convert with merge option checked on.
To migrate your Favorites to Navitel Navigator, save file in .GPX format, send it to smartphone/navigator, run Navitel and import .GPX to internal Waypoints:
How to import: Menu -> Find -> Waypoints -> Import (right-bottom corner in v.9.5.0) -> choose file
How to export: Menu -> Find -> Waypoints -> Export (mid bottom position in v.9.5.0) -> another .gpx file
Just import .KML file to newsly created layer. Enjoy.
Both should work with .GPX files import/export. Both software providers are oriented for own hardware in a first turn. Later versions are not consistent in working with favourites plus there are a lot of version forks for different hardware and a lot of them have a different functionality. So you have to check it by yourself.
CMU format will be downloaded as usbfavourites.zip, which should be extracted at the root folder of FAT32 USB drive. Procedure to download/update existing favourites:
To make a backup you can just download random usbfavourites.zip and run it without an update (answer NO in dialog).
