I tried to find anyone discussing this and couldn't seem to find it. I have a 2017 Model S. I brought her in for annual several weeks ago. I got a Model S as my loaner. The car was otherwise stripped from what I could tell. The loaner had this cool Caraoke function on the touchscreen that my GF loved. I got my car back, I've updated to the latest software update, and I still don't have it on my screen. Guidance?
