 So if you wanted the local search control to be at the bottom right of the map, 30 pixel in from the right and 20 pixels above the bottom and some local search options it would look like this:
 @map.control_init(:large_map => true, :map_type => true, :local_search => true, :anchor => :bottom_right, :offset_width => 30, :offset_height => 20, :local_search_options => "{suppressZoomToBounds : true, resultList : google.maps.LocalSearch.RESULT_LIST_INLINE, suppressInitialResultSelection : true, searchFormHint : 'Local Search powered by Google', linkTarget : GSearch.LINK_TARGET_BLANK}")
 
+==Sensor
+Google now requires the 'sensor' attribute in the GET API request. It is defaulted to 'false', but if you are writing an application for one of the new cellphones with GPS out there then you can enable it by using the following call:
+
+<%= GMap.header :sensor => true %>
+
 ==Recent changes
+- 'sensor' added to GET URL per Google API Terms of Use. 'false' by default.
 - Local Search overlay added. See above for implementation.
 - GMarker can now be placed by address (in addition to coordinates). Some code to geocode the address when the marker is initialized is added
 - Addition of a +center_zoom_on_points_init+ to center and zoom on a group of pixel
