Does anyone know where the OnStar (WiFi hotspot) device is located in a C7?

Probably in the dash, but I truly don't know. I can tell you it is not in the back, because I have had the entire back interior disassembled.

Interesting, do you know what the device on the driver side rear quarter is? It has a fan and heatsink on it so it's probably electronics of some sorts if I had to guess.

I also found what I believe to be 2 hi-gain antenna hidden behind the rear bumper above the license place, did you as well?

Yes I knew about the antenna!
I believe that is a cooling fan for the brakes and if I'm not mistaken they are only on the Z51 and Z06,but I could be wrong!
