Initial Setup and Connectivity
1. Bluetooth Connection
To connect your mobile device via Bluetooth:
- On the head unit, navigate to the 'Apps' menu and select the 'BT' (Bluetooth) icon.
- Go to 'Bluetooth Settings' and ensure Bluetooth is enabled. Note the device name (e.g., CarBT) and PIN (default 0000).
- On your mobile device, enable Bluetooth and search for available devices.
- Select the head unit's device name (e.g., CarBT) from the list.
- Enter the PIN (0000) on your mobile device when prompted.
- Once connected, 'phone audio' and 'music audio' should be displayed under 'Paired devices' on the head unit. If not, restart the Bluetooth connection.
2. ZLINK (Wireless CarPlay / Android Auto) Connection
ZLINK enables wireless CarPlay for iOS devices and wireless Android Auto for Android devices.

3. WiFi Connection (for ZLINK troubleshooting or general internet access)
If ZLINK connection is unsuccessful via Bluetooth, a manual WiFi connection may be required. This also allows the head unit to access the internet for map updates, app downloads, and online content.
- On the head unit, go to 'Settings' > 'Android Settings' > 'Network & Internet'.
- Select 'Hotspot & tethering' and then 'Wi-Fi hotspot'.
