Jason,
I tryed one of these headphone jack outputs in my car through the aux-in and wasn't very happy with it. I have to nearly turn the volume on the ipod to maximum so that it is at the same level as the cd player. I think that this will be introducing some noise into the system by doing this, but I am not sure. If I keep the volume on the ipod at less than half then I have to turn the volume on the car stereo up so loud that I have noise from the amp. Not to mention that sometimes I unhook the car jack and hook up my headphones and get blasted away. I think that the dock connector is the best (and most audiophile) way to hook up the ipod. I am looking into getting a similar ipod connector for my car stereo but it costs about $150. It also charges the battery and will allow me to skip through the songs in five play lists though the cd changer controls on the car stereo.
