The Complete Guide to Installing Apple CarPlay in Your Mazda CX-3

Your Mazda CX-3 is already a fun, agile, and well-designed compact SUV. But what if you could take that experience even further — by adding the power and simplicity of Apple CarPlay directly into your dashboard?

With Apple CarPlay, your iPhone seamlessly integrates with your car’s original screen, giving you easy and safe access to navigation, calls, music, and messages — all while keeping your hands on the wheel and eyes on the road.

In this complete guide, we’ll show you how to install CarPlay in your Mazda CX-3, step by step. Whether you’re a DIY enthusiast or a first-timer, this guide will help you complete the upgrade confidently and safely.

Why Install Apple CarPlay in Your Mazda CX-3?

Integrating Apple CarPlay into your Mazda transforms how you interact with the MZD Connect system.
No more reaching for your phone or juggling apps while driving — instead, you get an intuitive, familiar interface designed for use on the road.

You can:

• Navigate using Waze, Google Maps, or Apple Maps

• Stream your favorite music from Spotify, Apple Music, or Deezer

• Use Siri to send messages or make calls hands-free

• Enjoy full steering-wheel control compatibility

It’s a simple upgrade that adds modern convenience, safety, and resale value to your CX-3.

Step 1: Check Compatibility

This installation applies to Mazda CX-3 models equipped with the MZD Connect system, typically from 2016 to 2021.

Your software version must be 70.00.21 or higher.
To check:

• Go to Settings → System → About on your Mazda Connect screen.
  If your version is lower, you’ll need to update it through a Mazda dealer before proceeding.

Step 2: Prepare Your Tools and Workspace

Tools You’ll Need:

• Mazda-compatible Apple CarPlay & Android Auto module (available from TheCarPlayer.com)

• Phillips and flathead screwdrivers

• 10 mm socket wrench

• Plastic trim removal tools

• Soft cloths or masking tape

• Cable ties for neat wiring

Safety First:

1. Park your vehicle on a flat surface and engage the handbrake.

2. Disconnect the negative battery terminal to prevent short circuits.

3. Protect your center console with a soft cloth to avoid scratches.

Step 3: Remove the Center Console

This might seem intimidating, but with the right tools, it’s simple.

1. Remove the rear trim of the center console using your plastic trim tools.

2. Unscrew the control selector and disconnect its cable.

3. Unclip the side panels (driver and passenger side) to reveal the MZD Connect screws.

Take your time — careful disassembly ensures a clean reinstallation later.

Step 4: Access and Remove the MZD Connect Unit

1. Use the 10 mm socket wrench to remove the retaining screw holding the main unit.

2. Gently pull the screen toward you and rest it on the soft cloth.

3. Disconnect all wiring harnesses at the back. (Tip: take a photo to remember where each cable goes.)

Step 5: Connect the Apple CarPlay Module

Now comes the exciting part — integrating your CarPlay system.

1. Plug in the new wiring harness from the CarPlay kit. It’s a plug-and-play “Y” connection, so no wire cutting or modifications are needed.

2. Connect the CarPlay module box to the new harness.

3. Secure the module behind the dashboard with cable ties to prevent vibrations.

Step 6: Replace the USB Hub

To use CarPlay, your CX-3 needs a high-power USB hub with Apple authentication.

1. Locate the original USB hub (inside the center console compartment).

2. Disconnect and remove it.

3. Route the new cable from the CarPlay module to the USB hub slot.

4. Connect and clip the new hub into place.

Step 7: Reassemble and Test

You’re almost done!

1. Reconnect the car battery.

2. Turn on the ignition and wait for Mazda Connect to start.

3. Connect your iPhone using a Lightning cable — the Apple CarPlay icon should appear.

4. Test all features: navigation, Siri, calls, and music playback.

If everything works perfectly, reassemble your dashboard in the reverse order.
Congratulations — your Mazda CX-3 now has Apple CarPlay!
