Operation and Phone Pairing
The ITZ-MYLINK system facilitates wireless or wired connection for both iPhone and Android devices.
Phone Pairing Process:
- Ensure your phone's Bluetooth and Wi-Fi are enabled.
- Connect to the ZZPLAY unit via Bluetooth.
- Once the Bluetooth connection is established, the system will automatically create an Ad-Hoc Wi-Fi connection in the background.
- For iPhones, this Wi-Fi connection will prompt as 'Use CarPlay'.
- For Android phones, select 'Android Auto' from the 'Setup > Smart phone > Android device' menu before using Android Auto.
- For wireless connections, pair the device via Bluetooth and follow the on-screen instructions.
- For wired connections, use a high-quality data cable to ensure stability.
Connecting to CarPlay/Android Auto:
- iPhone: After pairing, the system may prompt 'Use CarPlay'. Select it to launch CarPlay.
- Android: Select 'Android Auto' from the phone setup menu.
The system allows for contact and favorite synchronization. Users can choose to allow or deny this during setup.
Note: CarPlay will function without contact syncing.

Frequently Asked Questions (FAQ)
Q: I can't hear any audio from the CarPlay/Android Auto system.
A: Ensure your OE system is set to Bluetooth audio mode. The phone must be paired to the factory GM Bluetooth system for both phone calls and audio. AUX input is generally not used for this system.
Q: Sometimes my phone won't connect, the screen goes black, or CarPlay kicks me out.
A: For iPhone users, performing a 'Hard Reset' on the phone is recommended approximately twice a month. This clears cache and resets processors without erasing data. Follow the specific iPhone hard reset steps provided.
Q: Incoming text responses from SIRI are silent on CarPlay.
A: This can occur if the iPhone is connected to the vehicle's OE Bluetooth for both phone calls and audio. Ensure the phone is only connected for phone calls via OE Bluetooth. For iPhone, adjust phone settings in the OEM radio's Bluetooth/Phone setup to disconnect as an audio player. Some vehicles may not offer this option.
Q: Using Android, I cannot get the phone to reliably connect wirelessly.
A: Android phones can be more sensitive. Ensure the Android OS is up-to-date and clear the cache on the Android Auto application. Android OS version 11 or higher is recommended. Some phone models (e.g., TCL, Motorola) may have compatibility issues; in such cases, use a high-quality USB-C cable for the Android Auto connection.
iPhone Hard Reset Instructions:
- Press and Release Volume UP.
- Press and Release Volume DOWN.
- Press and HOLD the Main Power button for 20 seconds. Ignore the 'Slide to Power Off' slider; wait until the Apple logo appears before releasing the power button.
- Test the system after the phone reboots. This process does not erase personal phone data.
