Thread: Help with aftermarket stereo

So I am planning on putting a new stereo in my 2007 Grand Prix Base with the 3 button information center. I was told that i will need to get a kit to retain the door chimes and keep gauges functioning.

I found this kit on CARID and was wondering if it is all i need.

Let me know if you have had any experience with this.
Thanks
