I have tested many options which showed online. I believe this is Mazda car system problem. I found only released battery for a while. Screen came back, I reset to original manufacture state. After drive a while, it turned black again. I tested cell phone, radio. This problem is not from usb cable, or cell phone, or radio, or mute button.
A commonly reported complaint for Mazda CX-5 owners is that the car will not shut off properly. The engine shuts down, but the accessory power (battery) stays on . This issue has mostly been reported on the 2013 and 2014 model years.
