Oh, you are referring to the map version? That I am not sure. I've never kept track of that.In the past the MU5T-14H394-XXX has been blue cruise map updates. Not the actual module software.
Did you or your dealer do any FDRS updates? Particularly the IPMA?The reason why I asked is I tend not to use BC for multiple reasons. I used it last week for almost the entire drive to the cabin. It was much more smooth, less jerky, etc.
