Well, finally — it’s been 2+ months — and the dealer calls to say the part is in-house. So they scheduled for today to do the installation of the replacement touch-screen display. After a 3 hour installation, I am pleased to tell all that the display performs as expected. The “dead” right-hand side of the new display is functioning and I can once again use the settings to adjust the front/back speaker fade control up and down arrows. Thanks to the Chevrolet Customer Assistance Group in Center Line, Michigan at (800) 222-1020 or (586) 834-4780. My Senior Advisor, April, was never available to take my call. I called (865) 790-5600 Rishawnna (excuse the spelling) finally helped by contacting the dealership. I hope that I have better luck with this, my third, display. Bill H
