While taking my car for a ride, I was listening to morning radio and the speakers started popping. I started to smell a burnt electrical smell and saw smoke coming from the center of the dash. I turned off the radio and the smoking continued. So, I pulled over and shut the car down and the smoking stopped. I was able to pull the fuses to the radio and amp and drive the car home with no further smoking. Got a fault code of B1 5D814. Any ideas on the issue?
