How to reset the Mazda Connect infotainment system if you have issues such as the screen going blank or freezing, connecting to Apple CarPlay, or not displaying anything. I had problems with my Mazda backup camera showing a black screen, which the reset fixed. Other issues the Mazda Connect, including Samsung Mirror and Android auto, wouldn’t connect before resetting. Ensure that nothing is connected to the infotainment system when performing the reset procedure. Also, make sure your car is not started; just turn the ignition on. Finally, if the infotainment unit is getting no power at all, I would with checking your fuses.
