I searched the reviews on Amazon for your Pioneer unit (http://www.amazon.com/Pioneer-AVH-4000NEX-2-DIN-Multimedia-Receiver/product-reviews/B00IXPM03Y) and found this:

The app radio "integration" sucks, but I really don't have anything to compare it to. First, if you have an iPhone you'll need to run BOTH an HDMI and thunderbolt to the Apple HDMI to thunderbolt adapter and connect that to the phone - how do you make that look good/factory? Next, when hooked up like that you can't use the regular HU iPod integration or bluetooth audio and HAVE to use a less capable music app that you install on your phone (which then works through the app radio mode interface). There are also few apps you can run, and none with any exceptionally redeeming qualities that warrant not using the non-app mode capabilities. Also, switching back and forth between app radio mode and any other mode is clunky. If app radio mode and non app radio mode were more integrated then perhaps it would be useful? Perhaps if apps you had installed just showed up on the normal home screen like pandora, usb 1 and usb2 , etc. did it would be better.

I've read that there is an update coming soon with Car Play and other enhancements. I'm hopeful that this will fix some of the issues. I'm really hoping car play mode does away with the need for the HDMI adapter. We'll see in the coming months.

I'm not vouching for the accuracy of the review, I'm just passing it on.
