Do the Mazda CX-3, Mazda3, MX-5, and Scion iA Share the Same 7-Inch Screen?

Short answer: Yes. The 2014-2016 Mazda3, 2014-2017 Mazda CX-3, 2014-2017 Mazda MX-5, and 2016 Scion iA all use the same 7-inch Mazda Connect touchscreen digitizer, sharing the part numbers BHP1611J0D and K40005A29F. The 2017-2019 Toyota Yaris and Yaris iA (the Scion iA's successor after Scion was discontinued) use the same digitizer as well.

Why These Four Models Use the Same Screen

This isn't a coincidence of screen size. Mazda actually built the Scion iA. The car was based on the Mazda2, a subcompact that Mazda never sold under its own badge in the United States. Independent automotive reviewers have confirmed that despite the Scion badge, the iA was manufactured by Mazda using Mazda parts and Mazda's infotainment hardware. When Scion was discontinued in 2017, the same car continued as the Toyota Yaris iA, still built on the Mazda2 platform with the same Mazda-sourced infotainment system.

That shared manufacturing history is why the touchscreen digitizer, connector layout, and mounting dimensions line up across all four nameplates. The Mazda3, CX-3, and MX-5 from the same model years used the identical 7-inch Mazda Connect display hardware as their standard infotainment screen, so the digitizer that fits one fits the others.

Verified Compatible Vehicles and Years

• 2017-2019 Toyota Yaris / Yaris iA

Compatible part numbers: BHP1611J0D and K40005A29F.

What "Same Screen" Actually Means

The shared component is the touchscreen digitizer, the glass touch-sensing layer that sits on top of the display. It is not the full LCD assembly. If your screen shows a normal image but doesn't register touches correctly, ghost touches, freezes, or has cracked or delaminating glass, the digitizer is almost always the failed part, and it can be replaced on its own without swapping the entire infotainment unit or sending the car to a dealer.

Because fitment can vary by trim level and whether a vehicle was factory-equipped with navigation, always confirm your exact model year and screen size against your vehicle before ordering, even when your model appears on the compatibility list above.

How to Confirm You Have the Right 7-Inch Mazda Connect Screen

1. Measure your screen. Confirm the diagonal display measures 7 inches. Some Mazda and CX-5 trims use an 8-inch unit, which is a different part.
2. Check your model year against the compatibility list. Fitment years matter. A 2017 Mazda3, for example, uses a different digitizer (B61A611J0) than the 2014-2016 Mazda3 covered here.
3. Identify the failure type. If the display image is intact but touch input is unreliable, cracked, or unresponsive, a digitizer-only replacement is the correct fix. If the display itself is dark, dim, or showing lines, the LCD may also be affected.
4. Cross-reference the part number. If your vehicle's system documentation or a prior repair references BHP1611J0D or K40005A29F, that confirms compatibility with this digitizer.

Frequently Asked Questions

Does the Scion iA really use a Mazda screen?

Yes. The Scion iA was built by Mazda and based on the Mazda2 platform, which is why it shares Mazda's 7-inch Mazda Connect infotainment hardware, including the touchscreen digitizer.

Is the Toyota Yaris iA the same as the Scion iA?

Yes. When Scion was discontinued in 2017, the iA continued as the Toyota Yaris iA (and later the Toyota Yaris sedan) on the same Mazda-built platform, carrying over the same infotainment screen.

Does this replacement include the LCD display?

No. This is a digitizer-only replacement. It restores the touch-sensing glass layer while your existing LCD display stays in place.

Will a 2017 Mazda3 use the same screen as a 2016 Mazda3?

No. Mazda changed the digitizer design for the 2017-2018 Mazda3, which uses part number B61A611J0 instead of BHP1611J0D. Always confirm your model year before ordering.

Do I need dealer programming after replacing the digitizer?

No. This is a direct hardware replacement and does not require dealer programming or software setup.

Bottom Line

The 2014-2016 Mazda3, 2014-2017 Mazda CX-3, 2014-2017 MX-5, 2016 Scion iA, and 2017-2019 Toyota Yaris/Yaris iA all share the same 7-inch Mazda Connect touchscreen digitizer because Mazda built all of them on shared infotainment hardware. If your screen is cracked, ghost touching, or unresponsive, you're very likely looking at the same fix regardless of which of these four badges is on your steering wheel.
