6.1 Switching Between Systems

The kit allows for a seamless one-key switch between your original car system and the CarPlay/Android Auto interface. Use your car's factory controls (e.g., MENU button or a dedicated button, depending on your vehicle) to toggle between the two systems.

6.2 Using CarPlay and Android Auto

Once switched to the new interface, connect your smartphone wirelessly via Bluetooth and Wi-Fi, or via USB, to activate Apple CarPlay or Android Auto. This enables access to navigation, calls, messages, and music directly on your car's display.

Utilize voice commands (e.g., "Hey Siri..." for CarPlay) for hands-free operation of navigation, music, and communication features.

6.4 Mirror Link

Mirror your smartphone's screen to the car display to view videos and other content directly from your device.

6.5 USB Playback

6.6 Camera Functionality

The system supports your factory original reverse camera and parking radar. It also allows for the integration of aftermarket reverse cameras and 360-degree camera systems, enhancing parking and maneuvering safety.

6.7 Original Car Controls

The retrofit kit maintains compatibility with your original car's controls, including the mouse knob operation and steering wheel buttons, for a familiar and intuitive user experience.

7. User Tips

• Compatibility Check: Always double-check that your car's system is indeed CIC and has a 4-PIN LVDS port for proper compatibility and installation. This is the most common reason for installation issues.
• LVDS Cable Connection: If you experience a red screen after installation, the most frequent cause is an incorrect or loose LVDS cable connection. Carefully re-check both the input and output LVDS cables to ensure they are securely and correctly connected to the decoder box and the OEM screen.
• Professional Installation: While the installation is designed to be plug-and-play, professional assistance is strongly recommended if you are not familiar with car electronics or wiring to avoid potential issues and ensure optimal performance.
• Audio Quality: Utilize the built-in DSP and adjustable Audio EQ settings to fine-tune the sound to your preference for the best audio experience.

8. Troubleshooting

8.1 Common Issues and Solutions

• Red Screen After Installation: This issue is almost always related to the LVDS cable connection. Ensure the original LVDS cable from the OEM head unit is connected to the LVDS OUT port on the decoder box, and the provided LVDS IN cable from the decoder box is connected to the OEM screen. Verify both are 4-PIN and securely seated.
• No Signal / Black Screen:
  • Check all power connections to the decoder box to ensure they are secure and receiving power.
  • Confirm that the correct input source is selected on your car's display to view the CarPlay/Android Auto interface.
  • Verify LVDS cable connections as described for the 'Red Screen' issue.
• Wireless CarPlay/Android Auto Connectivity Problems:
  • Ensure your smartphone's Wi-Fi and Bluetooth are enabled and discoverable.
