Well, it's not really fully replaceable in your car without other work. That is, I have SXM in my car radio, integrated in the system. It's the only option. All else is bluetooth or cable plugins, a different interface to manage while I'm driving, and potentially additional costs (data costs, etc.).

Note that BMW and other "lux" makers are now offering deeper integration with phone apps... but they make you pay a subscription to them to enable said functionality. https://www.bmwusa.com/explore/connecteddrive.html describes it; half the features are free but traffic for the nav, integration with mobile apps, other features have an annual cost, around $50 US currently.

And yes, fair point on the 6 month complaint cycle being forced on us by obnoxious subscription approaches.
