But you have added a map into (original tomtom)FILES folder ??
The map must be copied into the second FILES folder.
PATH is : SD card root / Android / data / com.tomtom.europe (is empthy folder) / files (is empty folder) << here ALL tomtom FILES folder (with inside Europe map) and .metadata.xlm file.
If YES :
When you started TomTomo, you've selected Europe map??
Or, after selection, doesn't work anything ?
