I just picked up my car yesterday and in the Connected drive store was the option to have Carplay.
I paid up and by magic everything worked. I waited until this morning to check so perhaps it needs to download. It could be installed already and just needs to be activated, but either way it works.

To be honest I thought it would be better but I guess over time it'll improve.
