Your current mirror won't have the screen. GM sells two kits- one for trucks with nav that use the nav screen and one kit for those without that includes a new mirror. The nav kit is significantly less expensive because it doesn't need a new screen.

Any idea what the part number is for a 09 Sierra Denali?

Or at least where I can find it?

I have the NAV/DVD.
