This is a static archive of our old OpenStreetMap Help Site.
Please post any new questions and answers at community.osm.org.
Assuming you want to do that using Mapbox, there is a contact for technical support... https://www.mapbox.com/contact/
The openstreetmap.org site displays data from the osm database as rendered tiles and does not have layers of different categories of data to switch on or off as some maps do. You can display the gps traces or notes over the map styles offered.
It is an openlayers question. See the demo page for switching sources keeping the same focus
