GMC Canyon radio volume loss and equalizer memory issue not yet resolved on GMC Canyon

Some GMC Canyon owners report experiencing frustrating issues with radio volume loss and equalizer memory, where their audio settings reset despite radio stations remaining programmed. Many have found that performing a hard reset on the radio can help resolve these problems, although the reset button's location may vary. Despite attempts at various troubleshooting methods—such as unhooking the battery and pulling the radio fuse—some owners continue to face persistent issues. One user highlighted that this problem appears to be unique to the GMC Canyon, as they did not encounter similar issues in other vehicles using CarPlay. Additionally, some have reported sudden audio system malfunctions, including volume cutting in and out, a flashing clock, and an unresponsive volume knob. Users have suggested workarounds, like using a CH341a programmer to clone radio memory, as a cost-effective solution. To address the volume loss, one method involves holding the "Hang Up Call" button for 10 seconds while starting the truck, followed by pressing the power button on the volume knob to reset the system.
