Switching Radios

I assume there is a way to change out the stock radio. Only thing is most people I ask to do it claims its going to be costly because of the shape of the stock radio and aftermarket receviers wont fit into the bay.
Does anyone have an install guide or online reference into doing this? I have pretty good skills just didnt want to mess something up because its a new car.

Thanks in advance.

If you are wanting to remove the stock deck, I can tell you that the plastic piece of the dask around the deck will pop off with a little prying with a small screwdriver. Once that is off the deck unscrews with 4 phillips screws. Hope this helps.
