I am having problem with putting in the distance for the POI i can put in 250 meters but when i press DONE it doesnt do anything i have my OGG file in the same directory as my Custom POI and same name but it doesnt let me finish the setup.
Had same problem with my 920. The problem is you have the *.ogg file saved in the North America folder along with it in the sound folder. It confuses the tomtom. Delete the ogg files and only have the one in the sound folder and it should work for you. It fixed my issue.
