Can't sync via USB car

Can't sync via USB car
I had a friend give me an A1059 29GB ipod classic (I think it's 4th generation). Came with a large charger and firewire cable. When I try to connect it via the usb port in my car, no music or charging occurs. Is there a specific 30PIN connector I need to make it work? I've tried two others to no avail.
