That's good to know! I've had Sirius in my car since 2009, but use it nowhere else (Great for long drives!). I've been contemplating putting it on my phone but haven't pulled the trigger yet. I might, now.
I got it in a leased car in 2004. Grew to like it so much, that I got it in two more cars afterwards.
Got a handheld, too. Made three device charges of nearly $40 per month.
My wife bitched about that, until I started cutting back. I am no technical whiz. It took awhile.
My wife's car is only mid-level tech. Fiirst I showed her we could listen to XM, with her smartphone. Initially she wouldn't take the time to learn the steps. But her interest grew.
Learning to be patient, forthe vagaries of bluetooth pairing takes awhile.
Remember XM is competing with many music sources, like spotify, amazon, google, etc.
