Gigglemite

I am having this same problem. Just upgraded all the cables and firmware only to find the app mode doesn't seem to work. It says it's connecting to the iphone and the phone asks if I'll allow appradio, but nothing happens. Black screen and I can hear my music via Bluetooth. If anyone knows how to fix this please tell me. I am frustrated beyond belief. I used to have a high opinion of this unit, but am fastly changing my mind.
