Lets try and put radio in test mode with ignition key in KLR position radio on press and hold WB(weather band) until the MID displays a serial number release.
Several test modes will show go to Radio speed dependent volume control (GAL 1-4) to increase volume go up 1 lowest 4 loudest)
Hope this helps
