I have just upgraded to a new iPhone 4s from iPhone 3GS. when I plug my phone to the car via the USB port and select iPod from media, the iPod start playing with sound. Few minutes later, the sound disappear. When looking at the audio source in my iPhone, the audio source seems to be going through the bluetooth "My car" in the photo attached. I have to manually select "doc connector" from the audio source and few minutes later, it go back to bluetooth source.
Have anyone notice this issue with their new iPhone? anyone with iPhone 4s has been able to successfully use iPod with their S60?
