Same problem here- I just took delivery two days ago and came here to post but I’m glad I’m not the only one. I assume just needs a software update (hopefully).
I actually care less about Caraoke and much more that in the Model 3 I just traded, I can just say ‘’play ‘insert any music artist/genre’” and it would, and then continue to play similar music indefinitely. Now the MX just wants me to login into one of multiple paid services, which I don’t have and don’t want to pay for. I sure hope a software update will bring back free streaming music like the M3 had!
Btw, other then that a few small things, the car is amazing!
