I found a site that sounds like they sell something that can let you add another CD changer to your factory radio but its only for Non-navi people. They also sell like-bose amps incase you blow yours up. They also tell you have to add speakers and amps to your bose radio using their parts. Also they make kits that let you use the factory cd changers control and an aftermarket Cd changer. Unfortunely they don't have anything for an Infiniti/nissan bose system. so if anybody knows of someone else that makes a kit like this let me know. I don't want to spend Dealer prices to get my girlfriend a cd changer for her car. http://www.peripheral-aamp.com/peri_products_main.htm
