When I plug in my iphone 4S into my appradio the now launching app screen pops up and then that it. App lunches on phone but I can not get past the now launching app screen. If I open pandora it displays but thats the only app I get working. When i open the music player, music plays but the screen is blank. Finally I can not get the blue tooth to work. Any ideas? I only drive the car a few time a month if that makes a difference.
