🔧 *Audi MMI Radio & Navigation System Repair – Save Thousands on Dealer Repairs!* If your Audi MMI radio, navigation system, or display screen has stopped working, don't rush to the dealership. Many dealers will recommend replacing the entire MMI system, which can cost hundreds or even thousands of dollars. In many cases, the real problem is the *MMI control board* located under the center armrest. Due to its location, it is common for coffee, soda, water, and other liquids to spill onto the MMI control unit, causing buttons to malfunction, the screen to go black, or the navigation and audio systems to stop responding. The good news is that the MMI control board can often be repaired without replacing the entire system. Sometimes all it takes is a thorough cleaning of the circuit board and electrical contacts to restore normal operation.
