My 2014 Hyundai Accent won't play music. My radio is on, but no sound will come through.
This is not an unknown problem with this make and model. Sometimes the stereo system will start by losing sound on the FM radio, then progress through to the CD player and even the Bluetooth system. Eventually, you won’t be able to get any noise out of the unit at all. Apparently, it’s a glitch in the unit’s electronics and cant’ be fixed via a reset.
The advice is not to buy a second-hand unit from a wrecked car, as the same problem is likely to occur down the track. The good news is that there are companies in Australia that have developed a fix for this and can return your stereo to full working order. You can find them online.
The other solution would be to ditch the original stereo and fit something new with better quality sound and maybe even features like an integrated reversing camera.
