I just received my new 2008 SLT2 Acadia on Tuesday and this vehicle is AWESOME. I noticed that the computer and/or diagnostic cover is missing. It is located directly under the steering wheel. It is where they plug into the vehicle to run diagnostics, etc. Is there a cosmetic cover that goes over it to cover it up (maybe Acadia's do not have them) or is it supposed to be left open? Maybe the tech accidentally left it off when he was running through the car? Any help or insight would be greatly appreciated.
