Does DIYCarPlay supply the parts described in "Toyota & Lexus Head Unit Identification Before Ordering"?

Yes — the modules referenced in this guide are from our own catalogue, covering 19 vehicle brands and 39 head unit variants. If you are sourcing for resale, ask us for the wholesale and private label terms.

Can I ask a question about my specific car?

Yes. Send us your VIN (last 7 digits) and a photo of your factory screen on WhatsApp (+8613418827141) or email jerry@diycarplay.com, and we will confirm the correct module and what the installation involves.

Can you confirm this applies to my model year?

Head unit generation matters more than model year, because manufacturers phased each generation in over overlapping years. The compatibility table in this article lists the generations we have verified; anything outside it we will confirm case by case.

Toyota & Lexus Head Unit Identification Before Ordering

Quick answer: On Toyota and Lexus, identify by model line and build year first: the same dashboard layout can appear across several model lines, and the module split follows the vehicle line — TO-1 for the Sienna/Alphard/Prado/Tundra group, TO-2 for the Highlander/RAV4/Camry/Crown group, with Lexus split by generation across the IS/CT and the wider 2015–2020 range.

Who this guide is for: Toyota and Lexus owners, fleet maintainers and installers who need to match a specific vehicle to the correct decoder module before ordering.

Identification on Toyota and Lexus runs in the opposite direction from the German marques. On BMW or Audi, the menu style points to the generation. On these Japanese platforms, Toyota fitted related head units across several model lines within the same period, so the vehicle model and build year are the primary identifiers — the dashboard photograph confirms rather than decides.

Why model line comes first

Two Toyotas from the same build year can carry different head unit hardware depending on which line they belong to, and the aftermarket module that fits one will not drive the other. That is why our Toyota range is split by vehicle line rather than by a named infotainment generation:

TO-1 — the MPV and truck-oriented line: Sienna, Alphard, Prado and Tundra, 2014 to 2018.
TO-2 — the crossover and sedan line: Highlander, RAV4, Camry and Crown, 2014 to 2018.

Both modules cover the same year window, so the model line — not the year — is what separates them. This is the single most common wrong-part mistake on this platform: ordering TO-2 for an Alphard because the year matches.

Lexus: same logic, split by generation

The Lexus range splits by generation and coverage instead. LE-1 covers the IS and CT from 2013 to 2015. LE-2 covers the later window from 2015 to 2020 and extends across the IS, CT, RX, LX, GS, ES and LS lines. On cars that sit inside both windows — an early IS, for example — the build year settles it, and the covered list on each product page is the reference.

Dashboard cues that support the check

Once the model line has narrowed the field, the dashboard confirms it. The smaller displays with a physical control knob and hard keys point to the earlier configuration; the larger touch-first displays with a flatter bezel point to the later one. Photographing the powered-on main menu and the control area is enough for a confirmation — the same two-photo workflow used on every platform in this guide series.

Matching the module and what it keeps

On both brands the module sits between the head unit and the display, adding wireless and wired CarPlay and Android Auto while the factory screen, controls and reversing camera stay in service. Inside, it is an embedded Linux unit on a Sunplus automotive chipset pairing over dual-band 5 GHz WiFi — the combination that keeps wireless CarPlay free of the input lag buyers have learned to distrust. Nothing is coded or flashed on the OEM unit, and removal returns the car to stock — worth stating to fleet customers who run vehicles under manufacturer service contracts.

The covered lists live on the Toyota and Lexus fitment pages, and the fitment checker narrows a specific car in three steps. Models outside the listed lines — a Corolla, for example — are a separate retrofit: check the fitment pages before quoting, or send the dashboard photos through the contact form.
