How can I fix the audio system in my Kia Stonic?

My Kia Stonic's audio system is not functioning properly. The sound is distorted and I am unable to change the volume. What steps can I take to troubleshoot this issue?

First, try resetting the audio system by turning off the car's power for a few minutes and then turning it back on. If that doesn't work, check the connections to ensure they are secure and not damaged. You may also want to try replacing the audio fuse if it appears to be blown.

If the above steps do not resolve the issue, it is possible that the audio system itself may be malfunctioning. In this case, it is best to take your car to a certified Kia technician for further diagnostics and potential repairs.

Another possible solution is to update the audio system's software. You can do this by connecting your Kia Stonic to a computer and following the instructions on the Kia website. Be sure to backup any important data before proceeding with the update.
