I just had the AUX jack installed two days ago in my car. I just need to know what cable would be used to attach to either my Powerbook or an iPod with one end being connected to the AUX jack in my glove box. Since I don't have an iPod (I'm the last on the planet...putting it off for new updated versions) I'm not sure what the connection is that goes into it. I would imagine, maybe I am wrong, but if I were to go from the Powerbook would I use the headphone jack into the AUX jack of the car?
