No offense but you remove the stock head unit AND the cd player. Look down a few posts below this one. You'll see 2 posts by me. Pics of the wiring and plugs are there. One post right after the other. The stock head unit and the cd player go in the basement on a shelf. Ian is correct about the parts needed. When you buy the components, all the wiring and harnesses are there. Also, I installed the avic 7200 nex. Get a usb extension cable, plug it into the back of the 7200 (the correct port), and run it into your console. You can put many many tunes on a flash drive and play them through the 7200,outstanding. Also, download the pdf manual from pioneer. You can't imagine what all that stereo will do. The owner's manual that comes with it is 1% of what it will do. The install is a lot easier than it seems. Tell the installer to read my notes and he'll be fine.The plugs that wen into the cd get jumpers and just tuck them in somewhere. There's a ton of room. Good luck and let me know how it turned out. He should be able to do the whole thing in a day or two! Later
