Anyone have an idea on how to verify if I have the latest version?

Its funny, if you go to the official site the picture they show is an SD card not a USB but that could be just old and not updated. Will let you all know. Is there a place I can see the current map update to see if I am going forward or backward?

Well I found on Amazon where I can get it for less than $40. Its just a sim card. There is not a 2025 update yet just the 2024. I will try this. UPDATE: the SD card works and is recognized but it seems to be NOT the latest version of maps. Looking at the version info in the app, it appears to be the same as my 2022 version. Will have to return the update.

Mine is a 2021. I usually update every 2 years. Wife relies on it as she does not like to use her phone. I have a Garmin 890 I use when camper is connected.

Is there a place to get the update cheaper than the $149 on the GM site. I used to get an email with $99 deal but have not seen that in a few years. IMHO it should not be that pricey. $50 is reasonable.

How many miles is everyone getting on the factory tires? I have 23K right now and dont think they will make it to 30K. I have used Cooper At3 on previous truck so will probably go with that as I pull a 12K 5th wheel and occasionally get into some muddy conditions and of course snow in upstate NY.

This just out recently. Good news for all: 2020-2023 GM Silverado/Sierra 2500/3500 Truck 6.6L L8T Gas tuning has arrived! DiabloSport has combined their industry exclusive Locksmith device with the required ECM harness, and developed tunes specific to the L8T 6.6L Gas applications. The provided preloaded/preset tunes have shown gains of 28 RWHP and 50 RWTQ over stock, on good 93 octane gas! These are huge gains, that you'll feel when you stomp the go pedal! You can also adjust throttle response, tire size, speed limiter and more! For those that want numbers thats 429 HP and 514 RWTQ!!! on 93 octane

I will wait till someone posts a youTube video on how to do it. Mine runs about 205 when towing my 12K 5th wheel.

I know most people hate them and black them out but I would be interested in making the GMC letters stand out from the background by either a light smoke with the GMC letters cut out of a filtered paper over the GMC letters to make them a different color. Has anyone done this or know it there is a product out there?

Search this forum as there is a whole write up on moving the camera port to the bed. Pretty easy really except you have to purchase 2 extender cables for camera that they even give you part number and where to get. I did it and its very nice. Its along the level of the invisible trailer option not working for 5th wheels with the earlier models. Cant make it work on my '21 but heard its fixed on the '24s

I have plow option but be aware that it also includes the striffer front springs which does affect the ride somewhat. I did get the dual batteries also.Harness was included with the option.

I dont have it hooked up right now so cant answer that. I have an Andersen hitch so its supposed to be over the rear axle. If its not then its close. I see your thinking that if its too far behind it will offset the load on the front. The only way I could change that location would be an offset ball for my bed mount.

It's not the fact that I have too much squat ,its that the front end being so stiff it lifts a little when trailer is loaded. I have about 2" or less of rear end squat. I have sumo springs and Bilstein shocks on the rear. My trailer pin weight is about 2500lbs. Maybe my best answer is to get the lighter torsion bars for the front or start pigging out and put on 200lbs!

Wow, 78 views and no answers. Guess I have a tough one.

I have a '21 GMC 3500. It has the "snow plow" front suspension. So when I am towing the front end stays a little high. Can the torsion bars be adjusted to drop the front end by maybe 1/2 inch so that I may be more level when towing. I know an option would be going to a lighter bar but that is an expensive option. I don't mind if I have a little rake on the truck when not towing. So is there room to adjust? I know some crank them up for tire clearance. So will bringing them down accomplish my goal?
