We show you how to unlock all hidden functions in your car's multimedia system that come locked from the factory. We connect a phone to the car, search for Infotec Tutorials, navigate to the Mobile category and select Carplay Tips, then follow a simple process where we select our car's year, brand, and model. Once completed, the system becomes fully unlocked with all features working perfectly, whether your car is old or new. #CarMultimediaHacks #UnlockCarFeatures #CarplayTips #InfotecTutorials
