I'm guessing crmann is long out of the Z game...does anyone have his contact info by chance?
Does the unit still respond? It is common for the CCFL driver to burn out in these older units, its usually the culprit, and you can replace the tubes and drivers with led lines instead that will run quieter and longer too.
Use a bright flashlight and shine it at the screen to see if the panel is still lit up or if the unit is still responding to commands (press voice button).
That would be my first guess being that the screen went. With the details of this install, you should be able just to replace bits and pieces as the wiring and hardest part has already been done for you.
If it were me, I would install an aftermarket unit and relocate the screen as I did in my Z, everyone that has used the oem navi absolutely hates it after a while. Plus you get all the new features, and the oem buttons still work if programmed correctly
My unit sits behind the driver seat in one of the cubby holes which slide open when the eject button is pressed on the front, otherwise it is hidden.
Something to consider if you are bored of the oem unit. Most kenwood units work very well since the screen can be extended up to 8 feet away from the main unit. The screens are also LED backlit touchscreen which makes them nice for colder climates.
