Yes, the N900 built-in GPS. Even on the normal mode (not the simulation) the location is accurate on the map, but the view needs to be manually updated, by tapping the map. Even with "track" checked. And nothing on the GPS view.

With simulation, everything worked perfect.

Edit:

Oh, and would this thread be the right place to post feature requests? For the maps configuration, it would be nice if "box" maps in addition to "centerpoint" maps could be also configured.

With centerpoint maps I mean maps that use %(x), %(y) as centerpoint, but in Finland we have a map service that serves the map tiles based on topleft-bottomright coordinates. Example URL: http://kansalaisen.karttapaikka.fi/i...600&height=600

Unfortunately it does not serve map data outside Finland, so I understand that this particular service might be of no interest to you, but who knows, there may be similar services in other countries too?
