Most Current Audio Version Base XLT

[gjallen3]

Please forgive me if this question has already been answered, but I purchased a used 2024 XLT with the Base Audio System. I have tried searching for updates and nothing new has downloaded. My current version showing is G2.2.0.1_R23021A. Can anyone tell me if this is the latest version? As far as I can tell this version was updated in 2023.
