2013 Hyundai Elantra radio & backup camera problems

Radio and back up camera keeps going off. Light and everything is on but no sound

Those systems are integrated into the car’s electrical and data systems. There is no magic fix. I’d suggest taking it to the dealer to determine the problem.

There may be a separate amplifier for speakers and the power to it may also supply power to the camera. Power to those areas needs to be the first check for the issue.
