I'm buying a Tesla Model 3 and I have had a lifetime SiriusXM subscription since 2006. I've yet to transfer the subscription. Tesla appears to have NOT put a SiriusXM tuner in their new Model 3 so I need my own solution. Streaming from the phone would work but: 1) I do drive through some cellular dead areas 2) I hate the UI of the app on my phone. Speaking as a software designer (apps, website and more) for 35 years, my rating of the iOS app's UI is that "Yea, verily it doth suck mightily". So, looking at something I can install in the car, I see the Onyx radio that looks like a nice upgrade over the SkyFi units I used to use. Searching more, I find the SXBTD1V1 car cradle with Bluetooth on some sites - but it doesn't seem to be actually for sale anywhere and I can't find any information about it. What happened?
