A very warm welcome Munny
I can’t assist I am afraid but do believe near the end of 2016 they did get sync3… mine is May 2016 and sync2 but not rally arsed as not what I bought the RS for, in fact I often turn the display off, wind the window down and boot it!
Some great guys on here and sure they will assist you
