Geolocation Service for existing Flex Mobile Application

We have an existing Mobile Flex Application which has to be extended by an geolocation service to find the nearest dealer (within Germany). The search can be accomplished either by entering a German zip code or by using the GPS-Sensor of the device. A Wireframe of the planned view is attached to this project description. Once entered or retreived the location the user has to be taken to a new view which shows a list of about 50 dealers ordered by distance (ascending). The geolocation service intercepts a redirect from a productdetails page where the user has a button to visit an external shop system (web browser). Further more the user should have the option to store his choice permanently so that he will automatically take to the same shop whenever he clicks on the respective button in the product details page. The product details page etc. are already there. There is also a stub for choosing the dealer but without the geosearch. The geolocation of each dealer come as a JSON-File which is beeing updated from a webserver. You have to amend the database model in which the dealers are stored. The geolocation service must also be working without an internet connection. The project is build with Adobe Flex and uses the Robotslegs Framework. The code is stored on a git repository.
