Perhaps this has been asked before but: How can you connect a 4th generation Ipod to your home stereo. I have the 20gB version that does not come with a dock. There is a headphone socket but isn't the level on this to high for a Line level input to a stereo? Is there a cable available that plugs into the Dock port that brings out the Line out signal. The ones I've seen from Monster seem only to have a 3.5 plug on them.
