Car is W246. NGT5.1
It see only fw update 6.1 to 8. My map is 2015 which is very out of date. We have to figure also how to update.

All the day i tried to update and finally (maybe after more than 15 corruption) it updated without problem. Love the new interface.

In addition can anyone use the traffic info. For my country i think it s not supported for garmin map pilot but other garmin devices are supported. :S
