ok guys I know I'm not that bright of a guy. Can someone please tell me how I can hook up my avic n-1 to a extra car battery I have lying around the garage or some other way to power the sysytem up to see if it works! I searched the threads, but I cant seem to find the answer. Maybe you guys can tell me in detail in a thread or post a link where it a tuturial or something like that. I really want to find out if it works or not. Please help me out, thanks guys, David
