All you need to do is drag across the map element, enter an address (or use your current location), and hit enter. The map will update with your location.
You can update the map in the settings:
Map Location: Enter a new address to update the map. Map Zoom Level: Use the range slider to zoom in and out of your location. Map Style: Change the default roadmap style to satellite, hybrid or terrain. Map Controls: Enable pan, zoom, map type, scale, street view and overview map to display. Draggable map: Turn this on if you want users to be able to click and drag the map. Hide markers: Hide the red pin that marks the map location.
