  When you install a new car stereo, you may encounter problems that the car radio won’t turn on or off. What is the reason? Have you ever thought about the wiring problem? I hope this article can give you the answer.

Check from the most basic, whether your wiring harness is connected correctly, and don’t connect inappropriate wiring harnesses casually. If the wiring harness cannot be connected, you can ask the seller for help, and ask if you need a wiring harness that matches your model. If the problem still exists after the wiring harness is connected correctly, it depends on the problem of the car navigation itself.



Why the car radio won't turn on?

Here are the most common reasons that will cause a car radio won’t turn on:

  1. Car stereo wire connection:Check if your wiring harness is connected correctly and whether you need a special wiring harness for special vehicles.
  2. The car battery is dead: if your car’s battery has recently gone dead, that may be the reason why your car radio cannot turn on. When you turn on the ignition but the car radio won’t turn on, the installation of a new battery is a good way to settle the problem.
  3. blown fuse:For some reason, a blown fuse may be the culprit. The power surge may have damaged the fuse. If the car radio cannot be turned on suddenly, you can check whether the fuse is intact.

  1. The screen is broken:Overloading the car radio will cause the screen to burn out, but in this case, it will still have sound from the speakers or amplifier and the button next to it can still adjust the sound level. In such a situation, if your car radio is still under warranty, you can apply for a return or exchange with the seller.
