What is the MMI touch in the Audi A4 used for?

I am having trouble understanding the purpose of the MMI touch in my Audi A4. Can someone explain it to me?

The MMI touch in the Audi A4 is a controller that is used to access various functions such as navigation, media, and settings. It works by touch and swipe gestures, making it easy and convenient to use while driving.

I find the MMI touch in my Audi A4 to be extremely useful when trying to input information into the navigation system. Instead of scrolling through menus, I can simply write out the address or destination with my finger on the touchpad.

The MMI touch in the Audi A4 also has a handwriting recognition feature, allowing you to write and search for names, numbers, and other information using your finger. It takes some getting used to, but once you get the hang of it, it can save you a lot of time and effort.
