Hey all, im currently developing a S60 widget for Nokia phone.
I will demo this widget on the S60 emulator. In order to stimulate the situation, a .nme file is used.

Now the problem is , I got no idea when the tracker will move to the destination, because the purpose of this widget is, for users to select a destination and when the tracker moving on the map and hit the destination coordinate, it will pop-up a alert box to inform users that they have arrived the destination.

Is there anybody knows about .nme file and how does it works with the google map?
