Big-Screen Upgrades the Trim Fight For

A Truck-Owner's Guide to the Topdisplay Radio Upgrade for the 2022–2026 Toyota Tundra

14.5" QLED · 8-Core CPU · Touchscreen Stereo · Wireless CarPlay & Android Auto
Keeps OEM Controls

Why pull a perfectly good screen?

Old vs new: the factory unit next to the 14.5" Topdisplay waiting to take its place.

The 2022–2026 Tundra already has a big-ish factory screen — but next to this 14.5-inch QLED panel, it suddenly looks tiny. This Topdisplay swap drops in an 8-core CPU touchscreen with wireless CarPlay and Android Auto, and it does it while keeping every OEM control. No cutting wires, no losing your factory buttons, no going back to a screen the size of a phone.

The install is a little trim-heavy — these new Tundras like to be taken apart in a certain order — but the video makes it easy. Here are the moves that matter.

The Upgrade at a Glance

Step 1 — Loosen the trim from the top edge

The video starts at the very top: a trim tool pops the A-pillar and upper dash covers, starting with the passenger-side panel around the dash. Work the clips gently around the edge and lift each piece off — this is the gateway that frees everything below it.

Lifting the passenger-side dash cover — the A-pillar trim comes off first.

Step 2 — Pull the vent and the top panel

Next come the side A/C vent assemblies. The installer runs an electric screwdriver into the fasteners, then eases each vent unit out and sets it aside with its clips showing. The top dash panel follows, and suddenly the whole console is open and reachable.

Unscrewing the side A/C vent assembly before it comes out as one piece.

Step 3 — Lift out the factory screen, unplug it

With the panels out of the way, the video unclips the screen surround, reaches behind the stock unit, and frees it from its metal brackets. A trim tool works the rear connectors loose one at a time, then the factory screen comes out — leaving a clean opening and its harness waiting for the new unit.

Step 4 — Dress the new 14.5" screen with its bezel

Here's a detail that separates the pros: before installing, the video swaps the trim — removing the old black bezel and fitting a fresh silver one onto the new Topdisplay housing. Do this on the bench, not in the car. The screen is then prepped with its mounting bracket, ready to go in.

Fitting the new screen bezel on the bench before the unit ever touches the dash.

Step 5 — Pre-wire it: CANBUS, power, audio

Still on the bench, the harness comes together. The video shows the CANBUS decoder being connected (the cue on screen: "Connect Canbus"), then the power terminals and the multi-pin and AV audio plugs clicking home on the back of the unit. Building this bundle before install keeps the console work quick and tidy.

Connecting the CANBUS decoder into the harness — the clip that keeps OEM logic alive.

Step 6 — Meet the truck: plug and play in the console

Now bring the screen to the car. Match the new harness to the factory plugs inside the console — the video calls it exactly what it is: "Plug and play connections — simple and secure." Every connector is keyed, so it only fits one way. Once everything clicks, route the bundle so nothing binds.

Plug-and-play connectors seated — simple and secure, just like the video says.

Step 7 — Tuck the wiring and button it back up

Final stretch: the video spends its last minutes pushing the harness back into the console, keeping the cables flat and out of the way, and readying every panel for re-fit. No forced corners, no pinched wires — just a clean button-up. Fire it up, and your 14.5" QLED takes over: pair your phone over wireless CarPlay or Android Auto and enjoy the view.

The Bottom Line

Questions Everyone Asks

Q: Will this damage my truck?

A: No. It's a plug-and-play swap — the new harness matches the original connectors and no wire is cut or spliced. You can return to the factory screen whenever you like.

Q: Do I need professional tools?

A: Not really. The video uses a trim tool, a plastic pry tool and an electric screwdriver — nothing specialized, no soldering.

Q: Is the install actually hard?

A: No — it's more trimming than wiring. The 2022–2026 Tundra has a few panels to remove in order, but every step in the video is clear and the wiring is genuinely plug-and-play.

Q: Do I keep the factory functions?

A: Yes. The CANBUS decoder keeps the vehicle's logic and OEM controls working, so steering-wheel buttons and factory settings stay fully functional after the upgrade.
