Map Widget : Location 0,0

Map Widget : Location 0,0

Hi, i have Dragino Tracker D and when it is not able to send a GPS location it sends a default location of 0,0. Which is playing havoc with my opening of the map, because 0,0 is appearing on the west coast of Africa :), so the map cant zoom in because it has to include that location. Is there a way of getting the map widget to ignore that location? Or do you know if i can program the tracker not to send 0,0...or is there another way ...?

Thanks
Rob
