AVIC 8200NEX

Trying to mirror my Samsung S10 screen onto my 8200NEX display.

I bought a 'MircaCast' HDMI cable, or MHL as advertised by Pioneer. But I cannot get it to work.

Using a regular HDMI cable, my laptop mirrors beautifully to my NEX. 
Using the MHL cable onto a HDMI TV works great with my phone.

But for the life of me, I cannot get the NEX to work with the MHL cable with my phone. 

Using EZMira app. 

Any suggestions?
