Sorry I can't post any links yet but go to google and search "Fiat ecodrive". That's how I found mine - it will direct you to the Ecodrive part of the Fiat website and follow the instructions from there.
go on to the fiat.co.uk site, go to about fiat, then click on environment, a page will come up with a clickable button on the right saying something like download ecodrive! click on that, then follow the instructions!!!
