GPS window, no work???

I've had FS2002 for a couple of months now and I haven't really had much of a need to use the GPS window, but I thought I'd try to sort it out now anyway, as it just came to mind. ???
The Sim has been installed as per usual, there are no special circumstances etc to do with the install that I did.
When I select the GPS window, all I get is the black screen background, there is nothing on it. I have FS2000, and it works fine, so I know what it's supposed to do. ;D
So I just use the 'map' in the 'world dropdown menu' to navigate by eye.

What might the problem be? ???
