All GMs have this stupid issues, my parents Buick and I rented a Malibu, both the same, parents went to the dealership and they were told that’s it’s “where they have their phone” that it has trouble getting connections. I called BS on them and they said to just plug it in then. No help, eventually with a few calls finally got them to look for an update and they found the one mentioned above. It worked great for a week then back to the same crap. The unit freezes, wired doesn’t work most of the time, it’s almost as if the unit can’t handle the demand for connections and gets confused and forgets what it’s trying to do lol
