i read through most of the past messages regarding ipod connections for 2003-4 accords using the soundgate auxiliary input device for a direct connnection as the best option. i am in the process of purchasing all of the needed parts but i have a question about the install.

do you have to disconnect the stereo cable from the battery at any point during the installation of this device? my problem is my wife threw out a personal box that had the card with the stereo security code, and while im not 100% sure, im thinking that i will need that code if the stereo at any point is disconnected. thanks
