Not sure what you mean by "update" - but I went from Sync 2 in my 2013 to Sync 3 in my 2016. Sync 3 is much faster, and sorta does recognize speech a little better, and not "think" about it too long before it does something.
However, I find it still has that annoying step-by-step logic to it sometimes.
Sync 3 1.0 to Sync 3 2.2 wasn't worth it except for the Android Auto. The voice it uses to speak with is slightly different, and I don't like the change. It sounds slightly more garbled sometimes, when reading text or messages.
