2021 Sierra Denali 1500. Just thought I post something I discovered this past week. Out of the blue I had a major issue with my Bluetooth creating some unusual background noise. I could hear the other party fine but they could barely hear me (sounded like loud snoring background noise) it was bad enough that I couldn’t use the Bluetooth connection at all.
Tried everything, unpairing, repairing, reset network, unplug battery, swapped phones, factory reset on truck etc. I literally dealt with it over a week troubleshooting this.
I was about to give up and use a portable Bluetooth device however I found the culprit. Turns out the problem was a small envelope tucked under my passenger visor. It only covered about 1/2 the microphone on that side. When I noticed it, I remember thinking there’s no way could that be the damn problem…sure enough!
Anyway wanted to share just in case someone else is having a similar issue & save someone some grief.
