The install at a glance

Steps 1-4 are from our Tacoma install video (the wiring is the same). Step 5 is a customer's Corolla.

Description:

Looking for a Toyota Corolla radio upgrade with Apple CarPlay or Android Auto? This adapter harness plugs into the factory radio connectors of an Entune 2.0 era Toyota Corolla. It lets you install an Entune 3.0 head unit from a newer Corolla (or another Toyota) in its place. Most of the Corollas we have built it for are 2017 models, including the LE, SE, XSE and Corolla iM. The factory microphone and steering wheel controls are retained.

Toyota Corolla install notes

These notes come from the Corolla installs our customers have done with this harness. Most were 2017 Corollas. For a 2019 or newer Corolla, or if you aren't sure which radio you have, please contact us with a picture of the connectors on the back of your radio before ordering.

Which Entune 3.0 head unit to buy

We recommend an Entune 3.0 unit from a 2020 or newer Corolla. The install is cleaner because the existing brackets from your radio fit, and the Corolla units usually cost less than Tacoma units. Corolla part numbers that customers have used with this harness include 86140-12210, 86140-12350, 86140-12540, 86140-02E71, 86140-02A50 and 86140-12531. If the unit is from a 2019 or 2020 vehicle, check that it has Android Auto if you need it, because some early units didn't.

A Tacoma Entune 3.0 unit also works with this harness, and several customers have installed one in a Corolla. The Tacoma unit's metal chassis sits on the upper half of the screen, while the Corolla unit's chassis sits on the lower half. With a Tacoma unit you may need to modify the mounting brackets.

Removing the bezel on 2020+ Corolla units

Entune 3.0 units from 2020 and newer Corollas are "tablet style": the screen sits in its own plastic bezel that sticks up out of the dash. That plastic trim comes off, and you mount the unit with the brackets from your current radio.

Navigation units: please contact us first

We have not seen a US Corolla Entune 3.0 unit with a separate navigation box. Every Entune 3.0 unit has a MAP button on the front, even without navigation, so check the back of the unit for a separate box instead. If you plan to install a navigation unit from another model, please contact us before ordering. You would need the navigation version of the harness and a Toyota cable between the head unit and the navigation box.

Center display in the gauge cluster

Non-navigation Entune 3.0 units don't send song or navigation information to the display between the gauges. Everything else that shows on that display will still work.

Units that are not plug-and-play

Newer Toyota radios, such as the wireless CarPlay unit 86140-12C60 and the radios in 2024 Corollas, have different connectors for the AM/FM antenna, USB and GPS. This harness does not plug straight into them.

Known issues

-The radio's color scheme may not match the rest of your car, but everything works.
-If the clock shows "--:--", make sure the GPS antenna (white half-circle plug) is connected to the new unit, then try the hidden-menu method in this video.
-If the unit doesn't turn on, the main 28-pin plug is in the wrong socket. It goes in the white socket next to the black connector.

Good to know before you order

• Retained: speakers (and the factory amp on non-JBL vehicles that have one), aux input, steering wheel buttons, Bluetooth microphone and the factory backup camera. The camera plug is built for 2014+ vehicles by default; email us if you need the 16-pin version for 2011-2013.
• Dash display (MID): street names, compass and song info show in the instrument cluster only with a navigation Entune 3.0 unit. Non-navigation units do not send this information.
• JBL audio: needs a JBL Entune 3.0 unit plus the JBL amplifier from a newer vehicle, and our JBL kit instead of the standard harness.
• GPS antenna: navigation-capable units use a different GPS connector. This only matters if you install a navigation unit without its navigation box. See the connector photo.
• Lead time: every harness is hand-built to order. Most orders ship within 4 days. Email us if you need it by a certain date.
• USB: the USB adapter keeps the factory console USB port that is connected to the audio system. Other USB ports in the vehicle that are not wired to the audio system (charge-only ports) are not connected to the new radio.
• Prices: main harness $125, USB adapter $40, navigation adapter $65 (only for navigation units), JBL kit $280.

Purchase (Non-JBL Vehicles):

If you need the USB adapter, please order both parts below

Main wiring adapter:

This form will ask if the new Entune 3.0 headunit has Navigation. Please be aware, it doesn't matter if your current/existing audio system has Navigation. This only matters for the new, Entune 3 unit that you're installing. If the Entune 3.0 unit that you are installing has the extra navigation module that sits under the main radio unit, then you will need the extra add-on wiring adapter sold in this form. For the Model/Year of Vehicle, please only provide the model of the vehicle that you own. The donor vehicle is not important in this case.

USB Adapter:

The USB adapter is a separate cable that is used to retain the USB port in the center console. This adapter will be needed for using Carplay, Android Auto, or USB charging using the existing USB port that connects to your vehicle's audio system. This adapter plugs in behind the radio and will convert the connection to the proprietary USB connection for the new Entune 3.0 radio unit. Need Wireless Carpaly? A Toyota compatible wireless carplay adapter will work with the new Entune 3.0 unit to add wireless carplay to your vehicle. Here is an example!

Frequently asked questions

Which Entune 3.0 head unit should I buy for my 2017 Corolla?
A unit from a 2020 or newer Corolla is the cleanest install because the existing brackets fit and these units usually cost less than Tacoma units. Part numbers customers have used include 86140-12210, 86140-12350, 86140-12540, 86140-02E71, 86140-02A50 and 86140-12531.

Can I use a Tacoma head unit in my Corolla?
Yes, the wiring is the same, so the harness works. The Tacoma unit has its chassis on the upper half of the screen and the Corolla unit has it on the lower half, so you may need to modify the mounting brackets.

Does it matter if my current Corolla radio has no navigation?
No. What matters is the Entune 3.0 unit you are installing. If it has a separate navigation box, you need the navigation version of the harness. We have not seen a US Corolla Entune 3.0 unit with a navigation box, so please contact us first if you plan to install a navigation unit.

The unit I bought has a MAP button. Does it have navigation?
Not necessarily. All Entune 3.0 units have a MAP button on the front. On a non-navigation unit, that button shows a message that the navigation app is not installed. Check the back of the unit for a separate navigation box.

Will I keep the microphone and steering wheel controls?
Yes. The harness retains the factory microphone and steering wheel controls when you install an Entune 3.0 head unit in your Corolla, including the Corolla iM.
