My current leased 2019 GLC300 didn't come with a satellite receiver either, but since we have a Sirius/XM home unit that we pay for, we have access to the Sirius app, which works great with CarPlay! It's actually better as it doesn't rely on satellite reception, which can affect stations when you're in a tunnel, in a parking garage, or under overpasses, etc. Since the pandemic, we've become a "one car family." My wife has the app on her phone and it works great! We don't even think about not having satellite radio at all, as the app does everything we want it to do!
