2022 suburban LS screen upgrade

[Asnsurfnut]

I’ve searched but no luck. I have a 2022 suburban LS. Diesel 4x4. I’ve decided to test if the larger screen that’s on every other model can replace the smaller screen that comes in LS now and PPV. The connections are identical and installation was pretty easy. Problem is the new screen displays 8 different screens in one lol. Dealer hasn’t been much help. I have an appt to see if it needs to be programmed. Just wanted to ask if anyone has ideas. Everything works btw. You can click any of them and it does what you want. I’d just rather have 1 big one..

Anyone?!

I would guess that there is some setting or control that is set up for the screen at the original size, and with the screen now being different, the controller may not know what it is supposed to do with the screen. Its possibly just a simple update at the dealer, but no idea if that is the issue. I am guessing you did this with the battery disconnected? It may not work, but it is worth a try to disconnect the battery again for a few minutes and then reconnect it and see if it works? possibly do several power up/sleep modes for your system as well, as it may be as simple as just needing to learn that the screen is different size and reset itself.

Thanks I did not disconnect the battery. I will try that! My dealer said they aren’t able to do anything because they can’t manipulate the code. They think it would need to be flashed from a trim level that had it equipped but they can’t do that. I’ve called several others and they say the same thing. I was hoping to be a successful Guinea pig in this but it’s not looking too good!

If it doesnt work, at least you know you gave it a try. And it will be here for when someone else will want to try it out to prevent them from doing the same thing. and if it does work, then that will be a nice trick.

Well, when the VIN on your Suburban is put in the GM system it will only do a reflash or update for the small screen because GM database knows that's what it came with. I know in years past if a different model component were used, the computer could be 'fooled' by using the VIN from a model that originally came equipped with that upgrade. That was in the Tech II days. The version GM uses now may not be susceptible to such manipulation.

The dealer probably wouldn't even try, but maybe an independent shop with a subscription would give it a shot if you're willing to pay. You'd have to get a VIN from a legit large screen 2022 Suburban, and ask the shop to use that ViN to flash the computer for your Suburban as if the new screen were a replacement part.

Not saying this is the solution because the system integration in today's vehicles is getting crazy complicated. Not to mention all the manufacturers are really trying to keep us from doing this sort of thing. Good luck.

Have you picked through display settings, if any, to see if there is one to not tile the display? Or a setting to change the display resolution?

Exactly. I’m sure I won’t be the last to try this.

I have and nada. Nothing I can find at least.

Exactly right. I’ve reached out to a few companies who might be able to help. I’ll update after. Thanks for the tips.

Well unfortunately no shop was confident enough to attempt. Old screen back in! Thanks for trying to help.

How many connections plug into it? can you restore to factory settings on the display?

There are two connections. I did restore to factory settings and did not work.

I’m still waiting for my LS to be delivered and was wondering the same. Thanks for trying so I don’t have to (yet) but certainly hoping one day this will be an easy upgrade!

How difficult was it to replace the screen? I see you had a a lot of your dashboard exposed not sure if I dare to do it on a brand new vehicle.

Btw - have you looked into replacing the instrument cluster with the full lcd ?

Full instument cluster lcd would be awesome to do as an upgrade for the ls. Somehow i dont think it will work. But we can hope amd i would definitely do it myself.

Well… It requires a decent part of the dash to be removed. Having said that now that I’ve done it it would take about 10-15 min. Ideally you would have to remove the center consol as well, but you can barely squeeze it out. I could make a quick video of you or anyone really needed it.

I have not considered the instrument cluster swap. I assumed it wouldn’t be possible or would cost too much. The screen to me seemed doable. With the same connections I figured they act as a monitor. I’m sure someone will figure it out but to be honest the screen is 5x better than my 2021 silverado screen that’s the same size. The suburban screen is much faster and feels way different despite the display looking identical to the silverado screen. I hope you try though and it works! But I’m content now. After the lift and tires of course.

One idea is still bugging me.. the screen I bought said new with a blemish and never installed… But, the screen was obviously used with no noticeable blemishes. My thought is maybeeeee it was defective. And that’s why it was pulled out of a suburban. Or maybe not and that’s just what happens. I just really don’t want to do this all over again. I did break two clips and I really hate doing that. The design on a couple of the clips are horrible and very weak. It would be close to impossible to not break something pulling it apart.

Any update on screen upgrade on 2022 suburban LS? Would love to get rid of the silly 8” screen. I do realize that on 2021 LS suburban, they had the 10” screen. But in 2022 they switched to 8” . If larger screen worked on LS in 2021 models, gives me hope it would work on 2022 LS. Any thoughts would be much appreciate

 

[Tinbadtin]

@Asnsurfnut do you remember the part number you purchased? After some googling I found there are (at least) two part numbers 84805427 and 84805425 for seemingly the same thing(?)… at least I was able to find both for sale. Was wondering which one you purchased and I may try the opposite.
