You can also use this [Only registered and activated users can see links. ] to extract the *.gpx to then recombine together with your own preferred audio and icons back into *.gpi, but as Roger says i don't think there's any easy way to extract the original sounds/icons. But if you want to replace the alerts, as i think you originally asked, you really would only want the gpx or csv info anyway?
