Hi, it seems there was. I bought my MY18 GLX+ last year in August, it was built in January 2018 and it has the Smartphone Link Display Audio system with Android Auto etc. It also has single zone automatic climate control in place of the manual a/c.
I remember seeing late 2017 builds when I was looking at buying a demo, and these had an older touchscreen audio system that was different to mine. I'm guessing mine is among the first with the upgrade.
Out of curiosity, does yours have manual a/c or climate control?
