iPhone 3G Accessories
What's the difference between the iPhone 3G and an iPod in terms of the connector for accessories.
My car stereo plays and charges iPods over the USB connector, but it only charges my iPhone 3G.
I've read about a lot of people having issues with charging the iPhone 3G, but their music still plays. I'm having the opposite problem, and I don't understand why.
What's different in the connector or the protocol between the iPhone 3G and an iPod in terms of music playback?
Edit: I don't get any message on my iPhone 3G when I connect it, it just doesn't do anything, and the car stereo says nothing is connected.
