Had the truck in for 1 of my free oil/tire visits today and asked about the chime volume. Like Hawkeye mentioned above, I got a "deer in the headlights" stare from the shop's supposed electrical guru. Kicking myself as I hadn't been back on this thread for a while and Donstar referenced an actual TSB. Grrr. Will take that with me next time I go back as I didn't have time today for them to research from scratch. I've ticked off many a person on the other end of my Bluetooth phone connection as the speaker sits right below the microphone. It's bad enough in the cab, but they say it's earsplitting on the other end. I've played with the radio's chime volume setting some more, but it honestly appears to do NOTHING at all in either direction. Same thing for automatic mirror fold (or something like that). Can't figure out what it does when enabled. For what it's worth, the reverse mirror tilt setting does work, but I don't like it. Too disorienting for me when trying to back with mirrors. Just my luck. The 2 settings I want to work, don't. And the 1 setting I don't care anything about, does. *sigh*

Oddly enough, I already have a couple of those from the exact same vendor! Mine are currently in the back. My kids are still in booster seats, and the extenders make it much easier for them to get buckled. As luck would have it, my daughter just crossed the age where she no longer needs the booster, so I may be able to relocate the extender. Great idea. Hadn't even thought about that. Has anyone fiddled with the chime module itself (or is it even reachable without major dashboard teardown)? I'm still thinking about a good foam wrap. Also wondered if a resistor could be spliced into one of the feed lines. The mechanical engineer in me refuses to give up.

I did find the setting, but it was already turned all the way down. I played with adjusting it both up & down but like SkiDoo, I couldn't tell that it was doing anything at all. There's another setting in the same area for auto mirror that I *think* is supposed to fold in the mirrors when parking. From what I can tell, toggling that setting on or off has no effect on anything either. Will have to read the TSB link when I have more time. Maybe there's a known firmware glitch where some of the electronic settings are being completely ignored?

At work right now, but I'll see if I can find it later this afternoon. Thanks for the tips. I'm gonna feel like a moron if it's in the settings and I just never saw it. Doh!

Any idea which menu? I'm pretty familiar with the electronics and I don't recall ever seeing that option. Maybe I read right over it, or else it's an option in your 2017 Silverado NOT in my 2015 Sierra.

Does anyone know a way to drop the volume of in-cab door chime on a 2015 Sierra? I don't want to simply unplug / fully disable, but man is that thing LOUD. Haven't tried to physically get to it yet, but the thought of wrapping in foam has crossed my mind as a possible solution. If I'm ever talking on Bluetooth phone when forgetting seat belt, it nearly deafens whoever is on the other end of the call. Thanks! ~Vol
