I have a 2012 Charger with the 8.4N uconnect that I would like to update the map. I finally found on the internet that I need to put the file on thumb drive and plug it in. So I took the CN North America 2013.10.img (that I downloaded from here) and plugged it in to the usb and got this error message.

All I put on the thumb drive was the img file. Do I need to also put the jcv, asr and 3Dmap file on it as well to get it to work? Any help would be appreciated.
