Well I had Eco Drive working on my Fiat 500 lounge an d was happy with it and last week I plugged in the regular USB drive I usually use and when I plugged it into my iMac nothing happened. Although it had worked a number of times in the past and found data on the USb drive it didnt this time and has'nt since. I am also not getting the Eco Drive on message on my dash like I used to but have been unable to figure out how to turn it back on. I have gone into the application on my iMac and re setup the USB drive but it makes no difference when I plug it into my 500. Any ideas guys ?
