For probably 2 years now my 2015 Chevy Silverado 1500 has been experiencing a strange issue that my local dealer was kind of useless in fixing. The radio works perfectly fine with one exception: whenever the radio is switched from Bluetooth or XM (which work perfectly fine) to FM radio, it begins glitching to point that it does not function at all. It appears to reboot endlessly, no audio comes out, and no buttons on the radio work. In order to switch it back to Bluetooth, I have try to quickly switch the source from the steering wheel controls as it endlessly reboots itself. Anybody have any ideas as to how I can correct this? Is it a fuse, radiohead., or other issue? Thanks.
