Hi guys,

I just got finished replacing my nav LCD screen. Thank you to the member that created this guide, as I used this for guidance!

I bought a new screen from this guy and couldn't be happier. Fast delivery and quick response.

I will add a valuable lesson I learned during this process. If, during the process of removing the small connectors and wires from the back of the LCD screen board (before you unscrew the 4 screws that hold in the LCD screen) you somehow manage to pull the a wire or two from the actual connector, fear not. Simply trace the pin layout from each side of the wires and make sure they match on a 1-to-1 manner like this:

Pin 1 - Pin 5
Pin 2 - Pin 4
Pin 3 - Pin 3
Pin 4 - Pin 2
Pin 5 - Pin 1
etc.

All the pins/ wires basically connect in this fashion. I got really freaked out because I pulled two of the wires from the base of their connector and couldn't tell where they went back into. Then, by looking at the other pin layouts I traced the wires and realized they all followed the same pattern.
