USB not working car stereo

We all love listening to our favorite songs in the car, but what can you do if your car stereo USB port doesn’t work?

One option is to use a Bluetooth audio receiver, but that’s not the most elegant solution, although it works decently.

However, there are ways to fix this problem, so be sure to keep on reading.

What can I do if my car stereo USB port stopped working?

1. Use another USB cable

  1. Remove the current USB cable that you’re using.
  2. Get a new one and connect it to your stereo USB port.
  3. Check if it works.

This is a simplest solution if USB port is not working in car and you’re trying to connect a device via cable.

2. Try another USB drive with your defective port

  1. Disconnect your USB device from the USB port.
  2. Next, try connecting a different one to the USB port.
  3. Check if the issue is still there.

It’s possible that your USB device isn’t configured properly, or that it’s faulty, so replacing it is a great way to diagnose the issue.

3. Check for any compatibility issues between devices

  1. Disconnect your USB drive.
  2. Connect it to your PC.
  3. Press Windows key + E to open File Explorer and go to This PC.
  4. Right-click your flash drive and choose Format.
  5. Make sure to set File system to exFAT or FAT32 and click Format.
  6. Once the drive is formatted, add your files to it and try again.

Many car stereos don’t work with NTFS drives, so always use exFAT or FAT32 drives on your car stereo and other non-Windows devices.

4. Update firmware for both devices

  1. Locate the model of your car stereo.
  2. Download the latest firmware.
  3. Check the instruction manual on how to properly install it.

If the car USB port not working, it’s possible that firmware might be the cause.

5. Try using a USB drive with a smaller storage

  1. Disconnect the USB drive.
  2. Get a different smaller size drive.
  3. Transfer all your files to it and try it.

Sometimes a larger drive might not be fully compatible with your car stereo, so you’ll have to use a smaller size USB.

As you noticed, the issue with your car stereo USB not working can have a variety of reasons – compatibility, size of the disk, the power outage, a defective cable, and ultimately a defective USB port.
