Head unit install help

[Bworkman]

Hi guys im new here, just need some advise on installing my deck

First off i have an 03 Denali with bose, onstar, and factory rear dvd player. I have a Clarion vx409 double din head unit to install.

I'd like to know what i need to install this, id like everything to work as factory such as steering wheel controls, bose system, on star, door chimes and alarm, and the rear dvd player through the head unit (if possible)

Any info and part #'s of stuff i need would be greatly appreciated!

Thanks
