It's a pretty easy install. Make sure you get a set of panel pullers I use the cheap $5-$8 set from Harbor Freight. It's soft plastic and you don't have to worry about scratching your dash or console. The entire install took me roughly 45 minutes and that was with some special splicing because I have the Bose center-point system and they weren't really designed for that, however for you it should be plug and play. My only major complaint is the data cable is a bit to short. I installed mine in the bottom of my console (i hate having wires showing anywhere) and I had very little wiggle room with it.
As Regency suggested starting from the top and working your way down seemed to work best for me also. I have plenty of pics in my photo album of my install if you want to take a look.
