I was wondering if anyone knows how to change the way you control your iPhone through the USB port on my Alpine head unit. Currently, it takes over my iPhone and makes me control it on the actual head unit. I find this annoying. It's awkward.
My buddy has a JVC unit that allowed him to change that. His originally was controlled through the head unit, but he could change it so he could navigate through his iPhone, all while still playing music and charging through the USB port.
Anyone know how to change that?
