HDMI Adapter For Entune Radio

Does anyone know where I can purchase an adapter for the radio that's not going to cost over $250 like https://www.beatsonicusa.com/if02ep.html sells them, preferable something under $100. Maybe there's another cheaper way to get the iphones to mirror on the screen?

 

I use this:

I didn’t set up iPhone mirroring but it is an option

 

As im posting this, I found an AV adapter and it comes with RCA which then you would have to buy the adapter that goes from that to iphone... but it ships from china...
