Looking for someone in the Waukesha WI area that has a GM MDI that can program body computers. I have the new Tech-line connect, an open VIN slot and a VXdiags Nano and I can get the software from the GM server to my laptop, but not from my laptop thru the Nano to my body computer, just keeps coming up with incompatible devise in use error. I've done software and firmware updates and nothing seems to fix it. Gotten to the point where I just want it done - anyone in the area an expert at this stuff and has a real MDI?
