Can't speak specifically about replacing the display but last summer I added the navigation feature to my 2104 XLT. I had to remove the screen and replace the CPU (probably not the correct name) which is attached to the back. The entire process to remove and install the new CPU took no more than 15 minutes. I bought the CPU from a seller on EBAY located in the Chicago area. If you go to YOUTUBE you can find videos of how to do it but basically you pop off the two vertical sliver trim pieces on either side. That exposes a couple of screws, take those out, and there is maybe four other screws. Good luck
