Take the RED and YELLOW wires and tie them together. Now, go out to your car and pop your hood. Touch the red/yellow wires to the positive post and the black to the negative post. That will kick on the unit and the unit will work as long as those wires are connected. You can press eject during that time and the CD will come out.

Depends on the battery power and head unit. Some may offer very basic functions on such a low voltage others simply won't.
