Deploy "Use current location" for auto complete form

On the website: [login to view URL] there are two autocomplete forms for places. When the user has GPS and clicks in the field and if the field is empty, OR if the user clicks on the field and deletes the place (remembered place from previous visit) "use current location" should be shown below the field. In other words whenever the places input field is empty AND the user has GPS then "use current location" should be shown below. When the user clicks clicks on "use current location" the current google places API has to be used to find the location/street&city (using the lat, lon) and enter it in the field. Currently when the user clicks on an autocomplete place addtional details are lookedup (such as geo coordinates etc) and saved in hidden fields this also has to be done when the user clicks on "use current location". Basically you need to offer the possibility to use current location and when the user clicks on that the same actions have to follow as it currently already does when the user clicks on a place suggestion.
