Location Auto-detection

Hi there!
I am searching for plugin with such a feature:
I need to have a page, with location auto-detection, so if user opens the page, there automatically could be shown the nearest locations, which I set. Does Pro-Pack do this. If yes, could you give me a demo of it or a page link which uses this feature?
