@ HansGans09,
If you found a way to install personal POI's in to TOMTOM NDS please spell out when you put the .OV2 files.
What version of Android are you using?
Then show them on the map.
You show a blank map with no POI's to be seen.
If you say you have custom POI's installed they should show on the map all the time.

But I do not see any at all.

OR are these the POI'S that can with the maps you downloaded from the TomTom server???


Please give full details of everything you have done.
