Centre on a node in Extended GMap

I've just started using the new Extended GMap display (for some reason I couldn't get the standard GMap display to correctly display passed long/lat fields), and it works fine - showing the marker in the correct place, however I can't work out how to centre the map view on the node (there is only 1 displayed node on this map).

Any ideas? Is this currently possible with the Extended GMap view?

Cheers,

Edwin
