Help with Double Din

[AngelsTrojans]

I'm gonna finally treat myself to a double din tomorrow.
I just want to make sure I get everything I need with everyones help.
I have a 2004 Tahoe with Bose/ Onstar.

I decided on the Pioneer AVH-P4300DVD.
I know I need the GMOS-04.
Antenna adapter.
Metra 95-2009 Double Din Kit.
Steering wheel control adapter.
IPod Cable.

Is that everything I need?
Is there another wire harness I'm missing?

Also... Is there a rear view camera anyone recommends?
And is there something I can use to be able to output the video to the factory flip down monitor, or to retain my Rear Seat entertainment.

Any help would be appreciated.
Thank you all in advance.

Anyone out there that can help with this? I'm ready to do the dame thing with my 03 Denali, only with a Pioneer Z1. I want to retain chimes, disc changer, steering wheel controls, and RSE. Is this possible? What else is needed?

I did the pioneer 4300dvd in my 06 denali an OP you have all the right equipment needed to do the installation with the gmos you will still have all the factory chime onstar etc etc FYI make sure you set the gain on the gmos or else you will have no little to no sound

P.s I love my 4300 you went the right route on picking a HU

You won't be able to retain the 6 cd changer an as for the RSE I know for the avh4300 it's equipped with dual zone so you can hook up the RSE to play in the front an back or through all speaker or just the headphones for the kiddies

Thanks for the help 06.
I'm starting to receive all the parts hopefully I'll be able to install this weekend.
Did you find it difficult to include the factory overhead monitor into the mix?

I actually didn't hook up the factory RSE to my pioneer cause the kiddies have headphones so they watch what they want an I listen to or watch what I want ( while car is in park) lol but the installer said Its not that hard since the RSE was already hooked up to my factory HU
