Help: Installing a new sony cd deck in my '03...

I heard you have to take the whole dash off? is there an easy way? I've also heard people saying that you dont really need to buy the extra harness for the the airbags and chimes, and that the airbags still worked?
Thanks for your replies!

i'd suggest that you buy the harness and keep your chimes, it might bite you in the ass down the road if you don't... and yes you have to take your whole dash apart...
