It's pretty much just a pocket. The kit wont be needed if you have an existing pocket with a single din radio.
Your car does not have a "typical" kit made for the dash. You will be mounting the new radio "ISO" mount. http://www.installdr.com/TechDocs/999015.pdf
All aftermarket radios come pre-drilled and screws supplied to be ISO mounted.
If your factory radio was a double din, (or a stacked radio/cd) then you would need the kit. If your new radio is double din, then no kit is needed.
Regardless of which way you go, You must use the factory radios side mounting brackets and transfer them to the new setup
