I have a 2015 Sonata Limited Ultimate. Every single time my car turns on it defaults to Sirius XM and I know of no way to change this. I *do not* want Sirius XM and will never sign up. Is there a way to get rid of it from my infotainment or at least stop it from defaulting when I turn my car on? I want to blow my brains out starting my car and having to listen to 5 seconds of Sirius XM ads every single day. I have called Sirius they can't do anything and the dealership knows of nothing they can do either.
