Hi guys, i have a 2005 350z w/ bose factory system in the car. then i installed a new avic-d3 on my car. It played sound in radio mode, BUT NOT IN THE CD NOR DVD MODE. All wires are connected and i also connected the amp turn on(blue wire) to the blue/white wire but still did not work. I'm just wondering if any experts out there can help me with this situation. Does this mean i have to change all the speakers and amp?? Please help
