Follow these steps for initial setup:
- Plug in the Adapter: Insert the PTGTO Wireless Adapter into your car's USB-A data port. If your car only has a USB-C port, use the included USB-C adapter. Ensure it is plugged into a data port, not just a charging port. The adapter features dual-sided LED indicators for visible status.

- Pair via Bluetooth: On your phone's Bluetooth settings, search for the adapter's Bluetooth name, typically starting with "smartBox-xxxx". Select it to pair.
- Confirm Connection: Follow any on-screen prompts on your phone and car's display to allow contacts, favorites sync, and connect to CarPlay or Android Auto.

6. Maintenance
The PTGTO Wireless CarPlay & Android Auto Adapter requires minimal maintenance. Keep the device clean and dry. Avoid exposing it to extreme temperatures or direct sunlight for prolonged periods. Do not attempt to disassemble or repair the adapter yourself, as this will void the warranty.

- No Audio: Verify that your car's audio input is set to CarPlay/Android Auto. Check your phone's volume and the car's volume settings.
- Overheating: The adapter is designed with intelligent engineering to prevent overheating. If you experience unusual heat, ensure the adapter is not obstructed and has adequate ventilation.
- Lag or Delay: While designed for minimal delay, ensure your phone's operating system is up to date. A strong Wi-Fi signal from your phone is crucial for optimal performance.
