5. Setup and Installation
Important Pre-Installation Step: Firmware Update
Before proceeding with the physical installation, your car's infotainment system firmware must be updated to version V70.00.21 or later. If an older version of the CMU software is used, the CarPlay/Android Auto compatible USB hub may not be recognized.
Note: Remove any SD card from the system before initiating the firmware upgrade. Reinsert the SD card only after the upgrade is complete to ensure proper GPS and navigation functionality.
Consult your Mazda dealership or official Mazda resources for instructions on how to update your specific vehicle's firmware.
Physical Installation Overview
The installation process involves removing existing trim, disconnecting the old USB hub unit and cables, and installing the new HMYC hub with its accompanying cables. This process requires careful handling of vehicle interior components.
It is highly recommended to consult online video tutorials specific to your Mazda model for detailed visual guidance on trim removal and component access.
Connection Diagram

This diagram shows the steps for replacing the old USB hub. First, disconnect the old USB hub unit and its gray USB cable from the CMU. Then, install the new HMYC USB hub unit and connect the new gray/green and gray/blue cables to the CMU. Wrap disconnected vehicle wiring harness connectors with sponge tape to prevent noise.

Keep the USB ports clean and free of debris to ensure optimal connection.
8. Troubleshooting
If you encounter issues with your HMYC Retrofit Kit, please refer to the following common solutions:
- No Recognition/Connection Issues:
- Firmware Version: Ensure your Mazda's infotainment system firmware is updated to V70.00.21 or later. This is a critical step for proper recognition.
- Cable Quality: Use a high-quality, certified USB data cable. Faulty or charging-only cables can prevent data transfer.
- Secure Connections: Verify that all cables connected to the new USB hub and CMU are securely seated.
- Restart Devices: Try restarting your smartphone and the car's infotainment system.
- SD Card: Confirm that the SD card was removed during firmware update and reinserted afterward, if applicable.
- Slow Charging:
- Ensure your device and cable support PD fast charging.
- Verify the cable is a data cable, not just a charging cable.
- Intermittent Connection:
- Check for loose cable connections at both the phone and the USB hub.
- Ensure the USB hub is securely mounted and not subject to excessive movement.
- If using Android Auto, some users have reported success by downgrading and then upgrading the Android Auto app on their phone, or restarting the app multiple times.
- Touchscreen Not Working (Android Auto):
- Some Mazda models may not support touchscreen functionality with Android Auto. This is a limitation of the vehicle's system, not the retrofit kit. Control via the Commander knob and steering wheel buttons will still be available.
If problems persist, please contact HMYC customer support for assistance.
