Any Google Maps converters available?

Thanks so much for this package - its revitalised an old piece of hardware for me!

I was wondering if there is any Google maps converting feature available for this?

I've written a small bash script using gpsbabel below - but is this feature already available within the package?

#!/bin/bash
echo "enter a filename"
read word
 one=.gpx
 two=.kml
oneword=$word$one
twoword=$word$two
igotu2gpx dump >$oneword
gpsbabel -i gpx -f $oneword -o kml,point=0,trackdata=0 -F $twoword
echo 'done'

As you can tell, my coding skills are basic to say the least!

Was I wasting my time?

Is there a similar feature already in this package?
