  Tim PowersAug 20, 2025
  If your MAC Audio Car Receiver isn't powering on, the issue might be with the fuses or the system itself. First, check both the radio fuse and the car battery fuse. If either is open, replace it with a new fuse of the correct rating. If the fuses are fine, the system may be in an illegal operation state. Try pressing the RESET button, located in the middle of the left side of the front panel.
