If the stereo system on the Kia Soul isn’t working properly, you may want to perform a factory reset on it with these steps.
1. Locate the small reset button hole on the faceplate of the radio. It is usually located to the lower-right of the display, but is sometimes located at the upper-right of the display.
2. Use a paper clip or pen tip to press and hold the “Reset” button for 1 second. The entire system will reset.
