I Heart Radio is one of the Merceds apps choices. The first time I tried it, it gave me a numerical code to input on my computer. I did that and now when I select I Heart in my car, it tells me to wait and then I get a black screen. Anyone else experiencing this or having success with I Heart?

 

I have used it and it works, but very slow. With Carplay and Bluetooth, it is not worth it. Once my trial is up I will cancel that piece...
