Auto volume question

[Sparker133]

Not from what I seen sitting in all of them and reading AT4 is close to Denali
AT4X is close to the Denali ultimate
Sitting the at4x the fit and finish looks almost identical to the ultimate didn't look like the Denali I sat in.
the AT4X has all the same as the ultimate 12 bose speaker, full-grain leather (the reg Denali has synthetic leather) 16 way power seats with massage. There are some other things
Plus I could have bought a ultimate for the same price I paid for the AT4x. The AT4 was the close to the same price as the Denali

Thank COVID for missing features that previously existed but then went extinct! I too was disappointed to learn the scaled back version of many things and let's not talk about the laggy infotainment system!

My 2023 1500 6.2 AT4X has this feature. I’ve owned multiple vehicles that claim to have this feature and the AT4X is the first vehicke in which it actually works.

Hi everyone

I am new to the forum. I just bought a 2025 2500 AT4X diesel, I traded in my 2021 3500 AT4 diesel on it. I have always had Chevy or GMC vehicles.

Does anyone know where to change the level on the auto volume that changes the volume with the speed of the vehicle. I have gone though the infotainment system and I cant seem to find it anywhere.

Maybe its labeled something I don't recognize, I know all my past trucks had it I will be greatly disappointed if a 96k truck doesn't.

Get ready to be disappointed. It doesn't have it. Mine's a 24 2500 AT4 with the 7 speaker Bose and there's not that option, don't think the 12 speaker would be any different. As someone else mentioned it may be "baked in" to the head unit/computer now. The thing that really pissed me off was no HD Radio!!! Are you kidding me? Anyway, I found the 7 speaker Bose to be absolutely abysmal that I completely removed the Bose amp and ran an Axxess DSP that interfaces with the ethernet signal from the "head unit" and installed two amps, an 8 channel and a mono, replaced all my speakers and added tweets to the sail panels, and added a 10" JL in sealed wedge box under the back right side seat. Sounds incredibly awesome now. GM should be ashamed of the crap they are putting in $70-100K+ vehicles now. The non-Bose in my 2015 Silverado actually sounded better than the Bose 7 speaker in my 2024...that's pitiful.
