What is MMI system?
The MMI system (Multi Media Interface) is Audi’s multimedia interaction system. The MMI system offers three configurations: standard MMI basic version, MMI basic plus version, and a fully equipped MMI version. The standard version is equipped with a terminal and a monochrome display, controlling basic functions; the basic plus version adds TP memory and a digital sound system; the fully equipped version features a 7-inch color display and other advanced configurations
Why need to confirm MMI system？
When upgrading the screen in an Audi vehicle, it is important to confirm the MMI system version for several reasons:
-
Compatibility: Different MMI versions may have varying hardware and software requirements. Ensuring compatibility helps avoid issues during installation.
-
Feature Availability: Newer screens may offer features that are only supported by specific MMI versions. Confirming the version ensures that you can take full advantage of the new screen’s capabilities.
-
Performance Optimization: Upgrading to a screen that is not compatible with your MMI version may lead to performance issues or limited functionality.
How to Checking Your MMI Version Information？
Method 1: MMI Menu Navigation
Press "Setup" or "Menu" button on the radio.
Go to "Settings"
Scroll down to "Version Information"
Look for first letters and numbers of Software Version: (e.g. HNav_XX_XXXXX_X)
Method 2: Access the Red Engineering Menu (REM)
Refer to the table to find the specific button combinations for your vehicle model. These combinations will allow you to access REM with your version information listed in the first column of the table.
This guide will help you effectively manage and become familiar with the settings and specifications of your Audi infotainment system.
After entering the engineering menu, please refer to the Audi system specifications table below to determine your configuration type.
