Driving a Mazda CX-9 already delivers a refined blend of comfort, design, and performance. But imagine taking that experience one step further — with Apple CarPlay seamlessly integrated into your infotainment system. By adding our Mazda CX-9 Apple CarPlay retrofit kit, you’ll bring cutting-edge technology and iPhone connectivity right to your dashboard.
Apple CarPlay allows you to safely use navigation apps, take calls, send messages, and enjoy your favorite playlists — all while keeping your eyes on the road. In this guide, we’ll show you exactly how to install CarPlay in your Mazda CX-9, step-by-step.
Step 1: Check Compatibility
Before you begin, confirm that your Mazda CX-9 is compatible with the retrofit.
Most models equipped with the Mazda Connect infotainment system (2016–2021) are eligible for a CarPlay upgrade.
If you own a newer model, CarPlay may already be pre-installed. For older versions, you’ll need an aftermarket CarPlay module — available on TheCarPlayer.com.

This plug-and-play module includes everything you need: the wiring harness, USB hub, and installation manual.
Step 2: Gather Your Tools
Before disassembling anything, prepare the following tools to make your work smoother:
-
Phillips screwdriver
-
10mm socket wrench
-
Plastic trim removal tools
-
Masking tape or soft cloth (to protect the console)
-
Cable ties (for securing cables neatly)
🔋 Safety tip: Always disconnect your car’s battery before starting to avoid short circuits.
Step 3: Access the Main Unit (CMU)
The Connectivity Master Unit (CMU) is the brain of your Mazda’s infotainment system, located behind the center screen.
-
Remove the trim: Use plastic tools to gently unclip the trim around the center console.
-
Remove the climate control panel: Unscrew and set it aside carefully.
-
Remove the screen: Use a 10mm wrench to remove the securing bolts and pull the screen gently forward.
Step 4: Connect the CarPlay Module
Now comes the main part — installing the CarPlay retrofit module.
-
Disconnect the wiring harnesses from the CMU and plug in the new “Y” harness from your CarPlay kit.
-
Connect the CarPlay box to the harness and secure it behind the console using cable ties.
-
Replace the USB hub with the upgraded one provided in the kit — this ensures proper power delivery and Apple authentication.
All connections are plug-and-play, meaning no wire cutting or soldering is required.
Step 5: Update the CMU Firmware (if needed)
Some Mazda systems require a firmware update (version 70.00.21 or higher) to recognize CarPlay.
You can check your version under:
Settings → System → About → OS Version Information
If your version is outdated, update it using a USB stick formatted in FAT32 with the files provided in your CarPlay kit.
⚠️ Important: Do not turn off your ignition during the update process.
Step 6: Test and Reassemble
-
Reconnect the battery.
-
Turn on the ignition and let the Mazda Connect system start.
-
Connect your iPhone using a Lightning cable — the Apple CarPlay icon should appear.
-
Test navigation, music, and calls to ensure everything works properly.
If all systems are functional, carefully reassemble the dashboard in reverse order.
🎉 Congratulations — your Mazda CX-9 is now upgraded with full Apple CarPlay integration!
