I have an iPhone 4, with 4.2.1 firmware, I used to have a problem when I connected it with my Sony XAV60 back when it was 4.1, but now with the new update it plays just fine. The new problem is, I can't increase or decrease the volume on my stereo when connected, it works just fine when I connect other iPods. But with my phone it just doesn't. I have to go back to the radio increase the volume, then go back to the USB to listen. Does anyone have this problem... Pls help!!
I connect it using Via USB
