I bought my XT4 a week ago so I have a lot of newbie questions and here is another one. I've been doing a lot of reading on the XT4 and I have a hard time remembering where I read something which leads me to this question on Wireless APC an/or AA. I was sure I read that the XT4 had wireless APC/AA but I can't find the article I read anywhere. I Googled it and apparently it's coming but the 2021 Escalade is the Cadillac with it. Is it possible that it will eventually be a software download too slow it to work on the XT4?
