Ford's updating process for Sync 3, both auto-update and manual, is really bad. I recently posted a thread about how it never updated me from the original Version 1.0 in a year and a half of ownership from new. Then, I got a download message which said I had updated: to V 1.0, what I'd had the whole time. Then, that update messed up my 1.0,which I was fine with, and took away voice recognition.
This thread and others like it made me reluctant to try manual updating because of all the problems with it, and I don't even think I can on my Chromebook, so now I have to take it to the dealer to fix what Ford's auto-update broke. Annoying.
