One thing that irritated me about the Pioneer is that if you want to use App Radio, you need to use USB1 and the HDMI input. If you want to use Car Play than you also have to use USB1 but not the HDMI.
Since I did not want a bunch of cables hanging out of my dash (there is also USB2 and Aux), I got a couple of adapters and mounted them in my cubby.
Here are a couple of pics.
