How do i unlock my Panasonic Strada CN-NVD905U

I also have a cn-nvd905u. I called panasonic and the treated me like a thief because I didnt buy it from a "authorized dealer". After running across a bunch of fake directions, I finally found the ones that work. the directions are:
you need to touch the screen right above and below the white box that says "input ID Code" in this order and I guarantee it will work.

Right up, left up, left down, left up, right up, left up
Enjoy

There should be no code unless you've entered 1 before.

Its a security thing designed to prevent people from jacking it then install it into another person's car.

There is no known way to *reset* it if the code is set. So you better ask your wife or whoever had access to the car for the code.
