I just updated the firmware on my Z150 and followed Pioneer's instructions to a T. The radio still doesn't recognize that my phone is connected via the cables. It only recognizes it via bluetooth. The AppRadio button on the Z150 is grayed out so I can't select it. I've made sure that my iPhone 5 has the AppRadio app as well as the CarMediaPlayer app installed. Still nothing.
Anyone had better luck than me? Is there a trick I've missed? I've deleted the phone from the bluetooth settings on the Z150 and re-paired it (making sure to select "yes" when it asks if I'm connecting it via Digital AV and also selecting "Yes" when it asks if I want to use it for AppRadio mode). I've also tried turning off bluetooth on the phone to see if that was the problem, still nothing.
I'm going to contact Pioneer's tech support as soon as they get back from lunch, they are in Pacific Time.
