Just saw the news at https://ir.lucidmotors.com/news-releases/news-release-details/lucid-and-siriusxm-introduce-siriusxm-across-full-vehicle-lineup
Personally, I only use Spotify. But I do remember seeing people complaining not having SiriusXM. Glad they were able to add it retrospectively...
Exciting, hope I can got my soon. What's the version number? I asked CS to push me the one after 2.0.14, they told me that they are only pushing the next one out randomly :( Really wish I can experience the 2.0 UX on my roadtrip tomorrow!
