After repeated attempts to get help specific to having DSP, nav and 6 disc CD player, my experience is don't expect any help from Seicane if you have a problem. I wouldn't purchase one unless someone here has has been successful installing the exact factory components you have found an installer that is familiar with the unit prior to the purchase.
