I have just completed my maps update on the eight inch (which had the ECE 2017 software) Columbus unit. Having seen Romans video on his update and a comment on it, I approached it with a little trepidation. Needn't have worried though as everything went fine. Downloaded the ECE 2018 onto an Sd card. Having seen Romans (9.2 inch Columbus) video wasn't quite sure which format to use as he mentioned the xFat as did a commenter on the video. I formatted my card to xFat but when asked to unpack the software it only allowed me to down load in Fat32. When I inserted it into my Columbus unit it began updating. My only problem came after the software had loaded to 100%, a message popped up saying Error with software update and gave me two options - Restart or OK. I pressed restart but my unit went blank with a black screen. I thought I had a problem but then my unit showed the Skoda unit restarting. I checked the map software version and found that it had indeed been updated to ECE 2018.
