I purchased one of these for my 2007 LTZ
http://ecx.images-amazon.com/images/I/31KPWh4WbNL.jpg
from Amazon, I think I paid around $107, I see it is now $119 or so for the unit. It was a NEW GM Delco unit, and it plugged in and worked fine.
One thing I noticed is the following:
1) It had the Outside Air Temp (OAT) that read about the same as the one on my mirror, it was always a bit different, one or two deg is all..
2) The color of the screen matched perfectly
3) After driving a while it would start to goof up, and the blower would literally sound like it was blowing in an empty box. I did not notice this before, so I did the following:
1) I removed the front face and the buttons and put it on my original unit.
2) This was fine but I noticed that the color was a little different, and it was more dim than the rest of my buttons and lights... this bugged me so I removed it again and put in the display board and the new buttons from the new unit onto the old unit. So half of it is the NEW, the parts you see, and the other half is the old unit, the brains... works & looks perfectly now...
I just discovered that the part number 25932038 that is used for the Enclave & Traverse appear to be the same except for the front mounting bracket, This is easy to replace, so if anyone needed buttons, and these appear to be slightly less expensive if all you need is fresh buttons.
