Pioneer 4500bt App Radio

heatherZ13

I have the Pioneer avh 4500bt double din radio and cannot figure out how to make the apps work. I have an iPhone 5, updated the software and even bought the stupid over priced compatibility cable, but nothing works. I downloaded the apps I wanted on my phone and when I plug it in I choose the apps button from the main screen, it tells me to open "app radio or another compatible app" and when I do, the screen stays black... Anyone else have this problem and/or know what I may be doing wrong?

Thanks!
