Find your position quickly and accurately with the built-in Assisted-GPS receiver. The Nokia N900 works seamlessly with Ovi Maps to give you the quickest available route as you make your way from A to B.

Quoted from the official website. Please pay attention to the highlited part of the text.Sounds like navigation to me.
