12.3″ Full LCD Cluster Upgrade (T1 SUV) 2021-2024

(1 customer review)




This WAMS exclusive allows you to retrofit of a BRAND NEW (full warranty) fully programmed 12.3″ Full LCD Instrument cluster found in the 2022+ up-level version of your SUV into your 2021-2024 Yukon, Tahoe or Suburban.  Please make sure you read the ENTIRE Description / FAQ prior to ordering as some things have changed from the first time this product was added.

This product is 100% custom to your vehicle and options and will eventually have options for mods such as added HUD hardware retrofit etc. (custom options to follow after initial launch)

We setup all clusters for Navigation regardless as it will allow you to turn off the speed limit menus and simply enable them if you choose to later retrofit navigation. We’ve found this to be the simplest method to make everyone happy and negate the need to send the unit back for additional programming should you choose to upgrade down the line.

After installation you will also need to have a quick and simple (less than 5 minutes total time once setup and connected in vehicle) final setup procedure done by a GM dealership or shop with access to GM Techline Connect. We provide detailed instructions in the box on how to accomplish this to give to the dealer and it’s a very simple to the point procedure but necessary due to the enhanced security on these vehicles (and modules).

IMPORTANT: In order to utilize the Speed Limit Display or Phone, Media and Navigation menus you MUST have an IOK Radio. The IOK Radio is the 2022+ Android Based infotainment with Google Maps VS embedded maps. If you have an IOR equipped SUV such as a PPV Tahoe this wont really matter however if you have a 2021 with an IOS/IOT radio those menus will not be displayed you will only have “Info” and “Settings”. We are working on a retrofit kit to add the 2022+ Infotainment to the 2021.


PLEASE NOTE: These units are special order and subject to varying lead time beyond our control.

Q: How does this work?
A: You place an order for a cluster using the menus above based on your trim preference. Most people will get the normal Chevrolet/GMC offering with the silver bezel. If you have a Yukon and want the light up GMC logo on the bezel you may opt for the “Denali” Style selection which also has a glossy piano black bezel. Upon delivery you will need to install the unit and then go directly after have a GM Dealer (or other shop with Techline Connect access) run a quick setup procedure; instructions will accompany the unit.

Q: How do I know which radio I have?
A: You can find this information by scanning for the QR code on your build label (likely located in the drivers door jamb) and looking for one of the three radio types in these particular vehicles which are: IOR (8″ Base Radio), IOS (10″ Midlevel without Navigation) or IOT (10″ Uplevel with Navigation). NOTE: The Speed Limit display requires the IOK Radio with a data plan to function.

Q: Can you do this for Export (Metric clusters)?
A: Yes. Being Digital that is all programming.

Q: Ok can you make the 12.3″ all digital unit work in the 2015-2020 SUV’s?
A: No. Those utilize an entirely different electrical architecture.

Q: Will this work for my pickup?
A: No, this is for SUV’s only there is a different offering in the shop for applicable pickups.

Q: Will I lose any features?
A: If you have an IOR Radio no you will not lose any functions, if you have an IOS/IOT Radio you will lose the Media, Phone and Navigation displays; they will not be shown.  We are working on an upgrade path for the 2022+ IOK Radio into the 2021 to correct this.

Q: Will I gain any features?
A: You may gain some features as the 12.3″ clusters have slightly different menus. We can also enable things you have added such as indicators for front park assist. If you have added FACTORY options that your truck didn’t have please put what you have added in the notes section.

Q: I saw a “Service Column Lock” error briefly at first startup but its never comes back?
A: We have heard from several testers that this shows up once and is not seen again and there is no trouble code associated with it so at this point it appears to be “normal” after install.

Q: What is the HUD Retrofit Option?
A: This enables the unit to drive a heads up display. Yes it can be installed no we do not provide support for that end of it but you should reach out to HarnessDr.com for wiring harness info to make that switch. If you have forward collision alert and are not 110% set on doing the HUD upgrade we recommend you do NOT choose this option as it will disable the LED Forward Collision Alert indicator.

Q. Why don’t you ask for my Mileage? What happens to my odometer?
A. Your odometer will sync to your vehicle during setup at the correct current milage.

Q: What about my engine hours?
A: These will be carried over during setup as well.

Q: Do I need steering wheel controls to use this cluster?
A: Yes you need factory (or properly retrofit) steering wheel controls to interact with the menus on these units. Adding this cluster along with the proper steering wheel controls and harness from HarnessDR.com found HERE adds full audio steering wheel controls as well as cluster controls to boot to boot 8″ IOR equipped trucks!

Q: My MPG/Range at install is WAY off is that normal?
A: Completely Normal! The new cluster has no baseline yet. You should start to see it normalize (or be close to completely normal) after one full tank of fuel has been consumed and the vehicle filled up. The remote app may take longer to normalize as it uses a “lifetime” MPG reading.

Q: Do I need to send in my factory cluster?
A. Nope! We are sending you a factory fresh unit.
