Final Installation of Destination Override Switch for the Navigation System

So, the switch I ordered from Toyota came in today... It didn't exactly fit in the stock location of the dash, it was a bit too big... For some reason, there are two pieces of plastic protruding out about 1mm on each side of the cutout in the dashboard... I filed them down and the switch fit perfectly... I took it out and put in the original blank switch and it fit perfectly as well, in case I ever want to restore the car to stock... This completes the nav hack (for now)...

First Picture: Cutout on the dash taped up with electrical tape to prevent any marks in case the file touches the edges... The 2 metal files I used...
Second Picture: The final switch installed... I think it looks OK... Close to a factory appearance...
