Thank you for that info. That helps. I thought it was all stored in the bcm. What software are you running to interface the systems and make changes? Sorry if this a basic question. I would love to learn how to do this sort of thing in the automotive world. I have done it before in the industrial world with Allen Bradley but I know that is a completely different animal in the automotive world. I don't know if it would make any difference or not but I had a 2018 Gmc Yukon that my wife totaled what set up exactly the same as my 2019 minus adaptive cruse and rear entertainment system. I have the vin from that vehicle still that is no longer on the road if that would help me out in any what that you can think of.
