The most recent version of the Infotainment firmware that I've seen on these fora is 14.5.0C. That's the version mine is running.
I'm under the impression that your screen will say "You have the latest version" no matter what version you have. Mine had an older version for months, and still had that message. The only time mine has *not* said this was when it announced that it was ready to do an OTA update. (This was after I got my letter from GM announcing it.) It instructed me on how to do it. I did what it said, and mine no longer says 14.4.2. It says 14.5.0C and...you guessed it..."You have the latest version".
I'm surprised yours hasn't updated itself. Is your in-vehicle data plan still active? If not, does the vehicle have access to a WiFi signal where it's parked? If one of these two isn't the case, it can be done at a dealer. While there, you can have them do the "Hybrid Battery blah, blah" recall update at the same time.
There have been many reports of CP/AA issues, but I don't recall that "lag" is one of them.
