Add POI or PDI into TomTom Nav4

Hello everybody,
I wanted to install POIs on a Nav4 device, but it didn't work. I downloaded the Camper Icons from the forum and installed Winscp on my PC. I created a folder ovi2_icons in the folder "locations" on the device and copied the ovi and png files into it.
The icons are not displayed to me after restarting the device.
What am I doing wrong?
