Do you have something more specific on that? When, how, with the 2018.48.1 version?
I updated to 48.1 this morning then drove a bit and discovered the Navigate function had completely disappeared, even as an option from the system menu. Resets did not help so I called Tesla Service and we did some troubleshooting, during which I was informed 20 files of ~6GB each were queued for download via WiFi, at least one of which is a set of new maps. On completion it should then cause the orange update clock to reappear for the install.
While I found it hard to believe that there really is 120GB to download, or indeed anyplace to store it onboard, this new mega-map update is probably a prerequisite to NoA in Europe, even if the feature does not get activated in 2018.48.1
So far about 8GB have come down and the Navi for no discernible reason resumed working normally.
Will update with the final DL figure when the marathon completes through my mobile in several days ... or may have to look for a fast open WiFi to complete.
