Description:

Looking for a Toyota C-HR radio upgrade with Apple CarPlay or Android Auto? This adapter harness plugs into the factory radio connectors of a 2017-2019 Toyota C-HR that has the Entune 2 style radio (sold as Toyota Touch 2 or Touch 2 with Go in the UK and Europe). It lets you install a newer Entune 3.0 C-HR head unit in its place. Steering wheel buttons and the reverse camera are retained. Most of the C-HR harnesses we build go to right-hand-drive cars in the UK and Europe. Right-hand drive does not change the harness, and we ship worldwide.

Toyota C-HR install notes

These notes come from the C-HR installs our customers have done with this harness. If anything here doesn't match your car, send us a picture of the connectors on the back of your radio before you order.

Which C-HRs this is for

We have built this harness for 2017, 2018 and 2019 C-HRs with the Entune 2 style radio (Toyota Touch 2 / Touch 2 with Go). If your C-HR already has an Entune 3.0 style radio (we have seen this on a 2021 C-HR), this harness is not needed.

Which Entune 3.0 head unit to buy

-The donor unit we see most often is 86140-F4070, a non-navigation C-HR unit. Order the non-navigation harness and the USB adapter for it.
-Navigation units such as 86140-F4090 need their own separate navigation box (for example 86840-K0020) and the navigation version of our harness.
-The navigation box from your old Touch 2 radio will not work with the new head unit.
-The newest C-HR head units (86100-F4021 / 86100-F4023) use different connectors, and this harness does not support them.
-If your car has JBL, you need a JBL Entune 3.0 unit, the newer JBL amplifier and our JBL kit (see the JBL notes below).

Navigation units: please contact us first

There is little room under the radio in a C-HR for the separate navigation box. One customer had to squash the A/C duct under the radio to fit it and needed longer leads to close the trim. We have not confirmed a standard mounting spot for the navigation box in the C-HR. The cable between the head unit and the navigation box is a Toyota part that we don't sell. If you plan to install a navigation unit, please contact us before ordering.

GPS antenna

Non-navigation C-HR head units such as 86140-F4070 have their own GPS antenna jack, separate from the connectors used for a navigation box. CarPlay and Android Auto use the GPS time to connect, so plug a GPS antenna into the new head unit. If your car's GPS antenna was plugged into the old navigation box, move it to the new head unit. If you don't have one, we sell a GPS antenna that fits: AHH-GPS1.

Finding the USB plug

On some C-HRs with the Touch 2 with Go radio, the car's USB plug (a gray, square Toyota connector) is not behind the radio. It plugs into the old navigation box lower in the dash, so you may need to remove more trim to find it. Our USB adapter goes between that gray plug and the new head unit. We usually include a spare cable with a standard USB socket on the end, in case you can't use the factory plug (you would then not use the factory USB port).

Screen and button lighting

This is a known issue on some C-HRs with a documented workaround. The illumination wiring is built into our harness, so after installing, turn on your headlights and check that the radio's screen and buttons respond. If they don't, the car is missing the illumination wire at the radio plug. The fix is to feed the illumination signal from another circuit that lights up with the headlights (for example a dash switch) into pin 10 of the 10-pin connector. Contact us and we'll help you with it.

Fitting the new unit

The Entune 3.0 unit is a tight fit in the C-HR dash. Some owners have had to trim plastic behind the dash trim or on the top of the new unit's case to get it to sit flush.

Known limitations

-The clock may show "--:--". Connect a GPS antenna first, then try the hidden-menu method in this video. On some C-HRs the clock still won't display.
-In one install the AUX input did not work.
-Fuel and energy information on the new head unit is not always accurate.

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!

Please contact us if this form does not fit your needs.

Frequently asked questions

Does this harness work in a right-hand-drive C-HR?
Yes. Right-hand drive does not affect the harness or compatibility. Most of the C-HR harnesses we build go to right-hand-drive cars in the UK and Europe, and we ship worldwide.

Which parts do I need for my C-HR?
For a non-navigation Entune 3.0 unit such as 86140-F4070 you need the transplant harness and the USB adapter. You only need the navigation add-on if your new head unit came with a separate navigation box.

Can I reuse the navigation box from my old Touch 2 radio?
No. The old navigation box is set up differently and will not work with the new Entune 3.0 head unit. If you want built-in navigation, you need the newer navigation box that goes with the new head unit. Please contact us before ordering a navigation unit for a C-HR.

Will I keep the steering wheel buttons, reverse camera and hybrid information?
The steering wheel buttons and reverse camera are retained, and the harness connects to the hybrid systems. The fuel performance information on the new head unit is not always accurate.

The new head unit does not turn on. What is wrong?
The harness has two white 28-pin plugs that fit either socket on the head unit. The main one, with the power wires, goes in the socket next to the black connector. If the unit does not turn on, swap the two plugs. Nothing is damaged if they are the wrong way round.
