Lot's of excitement on the Sierra EV Forum on FB, not sure if it applies to Silverado's. You have to go to the service center to have this done, but apparently it ads turn signal activated side view video, possibly Chrome and other things. Info is still coming out. Apparently one person with a 2024 got these updates as well. I have a service appointment next Thursday, I'll hopefully have some of the updates on mine!

If this thing works, I'll give GMC credit for coming through!

I got my 2026 AT4. Literally the only glitch I found is that if you are in camera mode with turn activated side view enabled, when the turn completes and side view closes it bumps you out of the prior camera view into the general apps page. All other apps go back to the app as you'd expect. That and the recommendation for adding Camera as a choice for the 'three app view' are the only things I can find that should be done.

I have 26 AT4 Extended Range. Only glitch ive noticed is if I open hood while in truck then shut it the screen says key missing. You can ignore it goes away in 10 seconds and everything keeps working. Basically the key needs to be inside of the vehicle and the vehicle running for that glitch to happen.

following this since I miss the turn cameras while trailering! I saw this in one of the FB groups so hopefully others get some more information before I schedule anything. I know getting sidewinder wasn't the easiest so I don't expect this to be either

I have a 2025 Silverado RST......have had no notifications about this software upgrade yet. Will be watching this forum for more info. Once I see that it is "for real", I will schedule trip to dealer! Thank you for posting.

Got the big new software update installed in my Sierra EV. The dealership gave me a little bit of a hard time at first, but ultimately did it. In the video I discuss the experience getting it installed and what I found that's changed. Let me know if you have any questions!

(24 Sierra Denali 1st Ed) I ran into issues today during the drop off. The bad news is that no matter how I worded, providing the mnf file and the bulletin number posted everywhere, the service rep could not find the update. He said it was because my VIN wasn't tied to the update or something along those lines, and I looked like a crazy man trying to explain to him how it was all over various internet forums so it must be true.

Luckily, at least he was gracious enough to find a "work around" to trigger a reason to update the modules under warranty. I'm hoping that this will automatically pull up whatever the latest file is, otherwise it will have been a waste of time. On the downside, the one EV tech they have is not in, so I'm out of a truck for roughly 4 days. On the positive I'm cruising in the 25 Denali, which is nice so I can get a feel for the updates, some of which I've already noticed.

It was a roller coaster of a morning. I give props to the advisor for at least trying to help. However, I give poor marks to GM because I have to take my morning to do this rather than OTA, AND the service centers don't get access to this info ahead of time. How is it that I, the consumer, have more data and info than the service center. When these things roll out, there should be a nationwide campaign to make sure everyone is on the same page. This is the type of experience that leads me towards wanting a Tesla.

Question how was this tech looking up to see if the update was available for your vehicle? Where they looking up Vehicle VIN lookup tools? It will not show up in any Dealership software, unless GM has an open campaign for it... The only way to see the updates of the vehicle is to plug it into SPS and scan ALL the modules.

Also if they read 24-NA-143 GM said they should update the modules if the vehicle is brought in for ANY reason.

Yes that it is. Nothing noticeable for the 652.10.

My 24 is in for service and hopefully they will update it. On the FB group, there is 1 confirmed Edition 1 that received the update which added the side mirror cams and new video streaming apps. I'm excited! I wonder if it comes with hands on supercruise too...

MY26 vehicles did have hardware refinements, and changes, some modules were reduced, and I believe the Camera system was upgraded. This is some speculation based on what GM did with other Models. It's the only real thing that makes sense.

Could they bring it to earlier MY vehicles? TBD!

Confirmed turn signal feature for 2024 RST first edition. And MUCH a welcome update. Reduces the blind spot on the passenger side and helps when towing!
The first attempt at VWP, it didn't work. On my second trip to the dealership, I had to explain to the Tech about the USB/part 2 radio update. He didn't believe me at first and later admitted he skipped the USB update on the first day I had the truck in for service.

While on the subject of updates, I have a couple questions. I had a 2025 SierraEV Denali with a December build date that I bought in February. I received both OTA updates (N25-F172AE and N25-2498340) in March. Unfortunately, in May a kid smashed in the rear of me and totaled my truck. Saturday I picked a new one, this time with a May build date. Presently, it came with the N25-F172AE update but doesn't see any others.

Q1: with having a recent build date that is after the update release date, is there a chance I already have the other update and don’t need it?

Q2: I have seen a couple posts from DIY folks that have mentioned an amplifier update in addition of the A11 Radio update. Do we have any info on this update. I have to say that the new truck does have noticeably more bass than my previous one, so I’m wondering if it might already have this.

YES! Just got mine back, update complete! I REALLY like the sideview camera turn signal. Especially since mine has the flat passenger mirror. Don't care as much about the graininess, it gets the job done, and the size makes it easy to see. Great job GM! It really is the little things.

When I get more time I'm going to check out the other stuff. One thing on my list is to see if my see-through trailer cam works now. One can hope.

not very persistent, also present them with 24-NA-143 and tell them that service rep can't see the updates only the tech can once vehicle is plugged into SPS.

Working on that. Unfortunately, all this coincided with work overload and looks like I'm driving to Colorado for the week, so now I'm going to be doing last minute packing after work tomorrow. My camera is in the garage, I just need to be able to get a chance to plug it in. The only thing I'm not sure of is whether the trailer needs to be plugged in too for it to try seek the camera. I took my trailer back to park it on my in-laws property, so that's another potential hiccup.
