I overall enjoy the Apple CarPlay experience in my truck. Granted this is the first vehicle I've owned that had it, so I'm coming from a new user perspective. My truck doesn't have the built in Navigation, so I use CarPlay for those purposes and I like the flexibility of using different map/nav software (Apple, Google, and Waze). The UI is pretty basic, so I can't really complain about its features in regards to using the software. I almost exclusively use Apple Music for listening to music and so I like the split screen view that shows current song and map/navigation. My only real negative is that it requires me to plug in my phone via USB in order to use it. You'd think wireless CarPlay would be a standard these days, but sadly it isn't and I wasn't willing to fork over the amount of money needed to get that one small feature. In regards to text notifications and reading them out loud, I don't seem to have those same problems. When I get a text message I get a notification up on the screen where there's the option to select it and Siri reads it out loud for me.

As noted, you should be able to just lock the door while leaving the truck running. From my experience it's about 30 minutes before it shuts off after extended idle. This is with the fob on me and doors locked.

I'd say there might not be an upgrade path yet. 4 years ago on my previous 2014 Silverado I upgraded from DL3 mirrors to DQS power folding towing mirrors. The DQS mirrors weren't even an option in 2014. Now it required a pretty serious investment in time having to rewire the truck, but overall it was doable. I was able to work with pgamboa who provided valuable information, instructions, and a pre-built wiring kit I was able to use to complete the work. You can see his forum page to get an idea and see that it might be possible on these newer trucks.

Maybe it's all in my head or it's how I change my driving habits when towing, but it seems when I have a trailer attached I don't seem to have any braking concerns. When I detach it feels like I have to put more effort in stopping. I verified it wasn't my trailer brakes giving me a bit of extra stopping power by turning it down as low as they'll go. With all the fancy technology in these trucks, I wouldn't be surprised if braking auto adjusts based upon workload.

Looking at mine, the RPO code for my radio is IOR and the wire colors are Left front: +Blue -Brow/DarkBlue and Right front: +Yellow -Yellow/Black. Doesn't appear to be different between the different radio versions. You can look up your trucks wiring via GM Upfitters https://www.gmupfitter.com/files/media/photo/1291/20_Silverado_2500HD_3500HD_Electrical_Body_Builder_2019JUN21.pdf. The speaker wiring colors starts on page 245.

Awesome, thanks for the info. Looks like I know what I'm getting myself for Christmas I do believe adamc9115's response answers the question about whether there's a viable plug-and-play option for speaker upgrades.

These look like a good replacement. I'm guessing you still had to cut and splice these in to get them installed? Curious if there's an OEM speaker connector that can be used instead of having to cut into the wiring.

I recently did a 1300 mile trip from Ohio to South Carolina and back pulling my 9k lb travel trailer. I averaged 10-11 MPG at around 70 MPH through the trip. If the traffic wasn't so bad through the mountains, I could have pretty much set my cruise and maintained highway speeds up and down the grades. Super impressed with the performance of the truck.

These are the steps I followed to reset the radio in my truck: 1) Browse the radio menu's to Settings > System > Return to Factory Settings 2) Select Reset Vehicle Settings 3) Wait to reset 4) Select Erase Settings and Personal Data 5) Profit I reset my radio on 4/16/21 and I haven't had a problem since.

Figure I'd at least follow up since resetting my radio back to factory last Friday. The good news is that I haven't had any issues since I performed the reset. So almost a week problem free when it was happening pretty much daily. Reading the posts on this forum I'm starting to think it only effects trucks that do not have the memory function for setting drivers preferences based upon which key you are using. I've noticed it's really only people with lower trim levels that seem to have issues with the volume and EQ resetting. Hopefully this "fix" stays and others hopefully can do the same to resolve their problem.

I've had my '21 Silverado 2500 LT for almost 2 months and it's done this from day 1. Volume resets to a "medium" level and my EQ resets to all zeros whenever it decides to. It doesn't matter whether I leave it on FM, XM, Bluetooth, or plug my phone in or not; It has a mind of its own. I haven't tried resetting the radio back to factor yet, so I'll have to give that a shot and see how that goes. Hopefully GM figures something out and pushes an update to fix it, I don't really want to have to take it into the dealership if I don't have to.
