I exported a few POIs from POIBase and then imported the mca file into my navigator. This basically works without any errors. When I search for POIs, I get "Imports" at the end of the category list, but when I click on it, only POIs are displayed. No matter how I name the mca file. How can I not create my own categories in the imported POIs? It makes little sense if all our own POIs appear in one list. Especially for those who import a lot of their own POIs. How and where can I rename the "POIs" in the "Imported" category?
