1. Introduction
The AutoSky CarPlay TV Adapter + HDMI Cable Combo is designed to enhance your in-car entertainment and connectivity experience.

With the adapter, you can seamlessly stream your favorite apps like Netflix and YouTube using your phone's 4G/5G hotspot, eliminating the need to constantly plug in your smartphone. The included USB-C to HDMI cable further expands functionality, enabling you to mirror any compatible smartphone application, including videos, games, and navigation, making it ideal for vehicles without wireless connectivity or when a wired option is preferred.
This device is a plug-and-play solution, requiring no complex tools or permanent installation. It integrates smoothly with your car's existing USB/USB-C ports and maintains factory controls such as voice assistants, steering wheel buttons, and the OEM microphone for safe, hands-free operation.

3. Setup and Installation
The AutoSky CarPlay TV Adapter and HDMI Cable Combo are designed for simple plug-and-play installation. No special tools or permanent modifications to your vehicle are required.

- Locate an available USB or USB-C port in your vehicle. This is typically the port used for wired CarPlay/Android Auto.
- Plug the AutoSky CarPlay TV Adapter into the vehicle's USB/USB-C port. If your car has a USB-A port, use the provided USB-A to USB-C adapter.
- Once the adapter is powered on, a prompt may appear on your car's infotainment screen. Follow the on-screen instructions to pair your smartphone via Bluetooth.
- After successful Bluetooth pairing, your phone will automatically connect to the adapter for wireless CarPlay or Android Auto.

3.2. HDMI Mirroring Setup
The included USB-C to HDMI cable allows you to mirror content from compatible devices directly to your car's screen via the adapter's HDMI input.
- Connect the USB-C end of the HDMI cable to your smartphone or other compatible device (e.g., a TV stick, gaming console).
- Connect the HDMI end of the cable to the HDMI input port on the AutoSky CarPlay TV Adapter.
- Ensure the AutoSky adapter is powered on and connected to your car's USB port as described in Section 3.1.
- Switch the input on your car's infotainment system to the HDMI source, if required. The mirrored content from your device should now appear on the car's screen.
Note: For HDMI mirroring, your car's infotainment system must support video input via CarPlay/Android Auto, or the adapter must be able to switch to an HDMI input mode. Some car systems may restrict video playback while the vehicle is in motion for safety reasons.

5. Maintenance
The AutoSky CarPlay TV Adapter and HDMI Cable are designed for durability and require minimal maintenance. Following these simple guidelines will help ensure their longevity:
- Cleaning: Use a soft, dry cloth to wipe the adapter and cable. Avoid using harsh chemicals, solvents, or abrasive cleaners, as these can damage the surfaces.
