I'm not sure the best place to grab the cod from without doing this...
set the bes logs to http and http verbose logging. Go download the google maps from
Google Maps
then go look for the cod in the mdat logs. Put the URL with the get request at the end of it. Save the cod on your desktop (or whatever). Make your own alx. It's really easy to do. Take a look at another app and change it to match.
