Mr. Cummings

I finally got my 05 Maxima back from my X and start fixing her back up catching up on the maintenance. Well, I decided to attempt to upgrade to the stock navi. I moved my display screen back to its factory location. I tried a color screen from another 05 Maxima. The screen didnt illuminate so i went back to the original amber screen. Before I even cut a single wire my dash started acting crazy and now I have the following symptoms.


No blown mini fuses. I checked inside the car and under the hood.
I hear relays click when i turn the key, but no crank attempt from the starter.
I cannot shift out of park.
Headlights do not dim when I turn the key.
Fuel pump primes.
No Heating or AC data is displayed on the information screen.
Turn signals flash but do not click with light.
With the key in the on position there is a humming sound coming from under the hood that goes away when I unplug the Throttle Body.
Windows roll up and down.
Trunk lights do not work.
Dash lights still work.
Low fuel lamp is on.

I know there are several modules that can cause the car not start but can anyone help me pinpoint what I may have blown up based on my specific symptoms? I plan on replacing the Unified Meter AC Amplifier module and the Anti Theft Shift Lock modules first. Any help would be greatly appreciated. Thank you
