So what should I do? I called Pioneer, and they told me that I need the navigation disc because since it was out of a car for a bit, it rebooted itself. Its now looking for the navigation disc to load up the menus and such. Im going to get my seller, and give him some crap because he was supposed to send it to me, and never did. Meanwhile, does anyone have the old Navigation discs that they would want to sell me. Thanks for all the help, you guys are awesome
