Ok, here is what I have in a few cars I own:
AVX-X5600BHS, big brother to the one you selected, this thing is awesome!
GM-A6604 for front/rear speakers and GM-D9601 for the subs. You are looking at a better amp for the fronts/rears, nothing wrong with that! Mine kills my ears when cranked so I stuck with that model.
Pioneer includes a USB cable to go from the rear of the head unit to wherever you want it, I think it was about four feet long.
I do not remember if they included a 3.5mm cable or not.............
Not sure if you have a backup camera in your car already, nor do I know if you can use it with the Pioneer unit. I bought a cheap one through Amazon which has worked fine for me. This is in my Vette, have not put one in my truck yet, but ran a wire for it so I don't need to dig behind the dash.
If you want XM radio, that is a separate module you will need. I only use my USB stick.
I have not hooked-up the wire so I can watch DVD's, have no interest in that.
I did burn a few DVD's with MP3's, but once I used the USB stick, I don't use the DVD player anymore for myself. My wife has HER DVD in there for HER music. It is great, no more fighting between us!
I can't tell you anything about an install kit. I am using the stock BA head unit in my Camaro, I like the integration with the rest of the car, plus I "cheated" that system and made it sound pretty good without changing the front or rear speakers yet. I will, but for now I just have a dual 12" subwoofer setup and dual Pioneer amps, plus my "secret" where the stock amp used to sit!
