Today I have a new problem:
SPH-DA01/ ipod touch4 or iphone4S (all updated)
When I connect the radio to iPod/iPhone the radio screen goes black, if I push the home button show the main page correctly icons app and iPod couloreds but when I touch the app icon the screen return black!
I have try to reset with apposite button, reset on option menu, power disconnect... but nothing!!!
If I select iPod function listen the audio, but not video.
Does anyone have a solution?

Risolved! Was The interface cable! The new one it's more flexiblean different than the old.
