With OpenStreetMap data you have two options:
1) Add your data to the source, i.e. openstreetmap.org. You will then see your update when we release the next set of MCA files for that country. This way you can also share your data with others.
2) Import the data directly in to Navigator (this way your POI are not automatically added to the openstreetmap.org database). Download the import utility for Windows PC (http://download.mapfactor.com/digger_10_0_57_exp120101_8ca2c32e11.rar [edit link]) and create your own MCA file. Note, that this way you can import only points.
