Is the audio signal through the iPod's dock connector analog or digital?
I see alot of car head units w/ USB inputs and iPod control through the iPod's dock connector.
The manufacturers of these head units always say it's fully digital audio.

I wonder why these companies use analog connections with their av receivers vs. all digital with their regular head units

Using the digital output from the iPod requires incorporating a special "handshake" chip into the receiving device. In car audio, a big deal could be made about the interference-resistant digital connection, plus the USB could be used for thumb drives. But in home, generally nobody cares, and it is extra cost.
