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.

What cables are you using and where did you buy them.

I guess you are using a firmware updated appradio 2 or an appradio 3. In that case you need to change the App Connection setting to Others if you want to use 30pin.
