How to Install Wireless CarPlay in Toyota Prado 150 GX / GXL (2018–2023)

Factory Unit & Finished Result

The 2018–2023 Prado features a factory 8" touchscreen with a separate physical climate control panel below. The Extnix kit replaces both with a large CarPlay screen and a new digital HVAC display module — a clean, modern upgrade. Click any photo to enlarge.

Remove the Bottom Left & Right Trim Panels

Using a panel removal trim tool, carefully pry out the bottom left and right trim panels on either side of the centre console. Work slowly around the edges to release the clips without cracking the trim.

Remove the Factory Climate Control Unit

The factory HVAC/climate control unit is held in place by clips. Use a trim tool to release each clip around the perimeter. Once free, carefully pull the unit out and disconnect the connector from the back.

Remove the 4 x 10mm Bolts from the Factory Head Unit

With the climate control unit removed, you can now access the 4 x 10mm bolts securing the factory head unit. Two bolts are visible in the centre, and one on each side. Remove all four.

Pull Head Unit Out & Remove Factory Harnesses

Slide the factory head unit out from the dash. Disconnect all factory harnesses from the rear of the unit. Note the position of each connector — there are multiple plugs including the main harness, antenna, and accessory connectors.

Remove Air Vents from the Factory Frame

The air vents transfer from the factory frame to the new Extnix frame. Release the bottom clips first, then the upper clips. The red-circled locations in the photos show exactly where each clip is located.

Connect the Primary Power Harness

Connect the primary wiring harness to the vehicle's main power supply connectors. The harness plugs directly into the factory connectors — no cutting or splicing required. Ensure each plug is fully seated and clicks into place.

Connect the Secondary Harness

Connect the secondary wiring harness which handles audio output, auxiliary connections, and additional signal wires. Match each connector by shape and size — they are keyed so they only connect in the correct orientation.

Connect Steering Wheel Controls, Amp & Reverse Trigger

Connect the harness for steering wheel audio controls, the amplifier output, and the reverse trigger signal. These are clearly labelled on the harness as shown in the photo.

Connect the Factory Reverse Camera

Plug in the factory reverse camera connector to the camera input on the harness. This retains your OEM reverse camera — no aftermarket camera required. The camera will automatically activate when reverse gear is engaged.

Install the External Microphone

Route and mount the external microphone under the dash near the A-pillar or steering column area. The mic clips onto a suitable mounting point and should face toward the driver for optimal voice pickup during calls and voice commands.

Connect the Radio Antenna

Connect the factory radio antenna to the antenna input on the new head unit. This ensures full AM/FM reception is retained. The antenna connector is a standard ISO or fakra plug depending on your variant.

Install the New CarPlay Head Unit & Climate Control Module

Slide the new Extnix head unit into position, ensuring all wiring is tucked neatly behind. Connect all harnesses to the rear of the unit, then push it firmly into the dash frame until it clips in.

The new digital climate control display module simply clips onto the factory HVAC unit connector — it's a direct clip-on/clip-off replacement, no wiring changes needed. Once clipped in, push it into the slot below the head unit.
