I swapped mine out for a din unit. You will need the seal kit or use the old one if it is in good shape. I could have used the lens out of my unit but it was scratched so I picked up a new lens as well. I broke the the seat belt button when trying to remove the clip from the old unit. So you might need one of those as well.
I installed the oil gauge onto the new unit in the car so that I wouldn't have to disconnect the oil pressure line. Be careful when removing and installing the oil gauge. The very last thing you want to be messed up is that line. It breaks or leaks and your new radio will be ruined as well as your carpet...etc.
Make sure that you check the fit before you try installing everything on the new unit. The bezel has 2 posts on the bottom where you have self tapping nuts. ( I think they were self tapping.) These two posts slide into the front top of the center console and with the nuts tighten make for a snug fit. I had my center console and trim plate off while I was doing this so it was pretty easy to get everything apart.
It wasn't that difficult a job. Be patient and remember where all the pieces go in the center console.
