oh man, carpet is easy... assuming you got the right kind. but i found the easiest way to get started is to grab a can of 3M Super 90 spray adhesive, an pick a big flat surface on your console to start with. I start by spraying both the carpet and the surface and letting it air dry for 30 sec. to 1 min. then i lay down the carpet and press it flat. then just keep repeating that procedure and start folding it down across the surface.
it will certainly bunch up around corners, but that's easy too. Just cut the bunched up section right down the middle, lay the two flaps over eachother, and then make another cut right down where you want the seam to be. then peel away the excess and you have two flaps that match perfectly.
Lastly, if you get spray mount on the carpet, you can clean it up real easy with some lacquer thinner.
probably alot easier to see that in a picture or video of sorts, but if you run into trouble, just let me know! it's easy i promise!
