Thanks for the update. I'm in the same boat as you. I will wait to see if anything new transpires from the trip to the GM dealer.

Hi SoxFan904... Did you figure out why it didn't work, I have a 2020 RST with the IOS radio and Z82 trailer pack. Would like to try it as well but don't want to spend the money if it doesn't work. Perhaps a GM dealer can program the module? Any info you can provide is appreciated. Thanks.
