There is a sub menu to the Entertainment System version, it is supposed to be an engineers menu so be vary wary of what you touch if you do decide to view it.
This has been posted elsewhere on the forum but if you want to access the sub menu and sub component SW versions
Tap 5 times on the Entertainment System Version
In the pop up PIN window enter 200519
You will now have access to the sub menu
Again, I would be wary of what you select in this menu as you might have the option to brick the car, knowing MG software.
