I really can't understand how the Ipod is recognized via USB only yet Iphone requires headphone connection. It's beyond obvious the car can send audio through the USB so potentially another solution would be to have an app that makes the iphone emulate the ipod for output so the car thinks it's an ipod not iphone then it will play without headphone.
why does this even matter? I actually don't know, perhaps I just think it's unnecessary to plug in a headphone cable
The iPod requires a headphone connection. I have an iPod Classic, 120GB, and there is no audio with a standard iPod-USB cable and no audio without the proprietary two-tailed cable plugged into the data and headphone ports.
I don't know why GM chose to do it this way, and their cable annoys me because it's impossible to lay the iPod flat in the console, and if I think about it there's a digital-to-analog-to-digital-to-analog thing going on, but I'm really trying not to go into a nerd rage over what is a functioning and adequate if unimpressive audio system.
