1. Locate the original power cable connector.
2. Cock the snap on the connector and carefully pull out the fiber optic cable.
3. Locate the power cord for the new unit and plug the fiber optic cable into the correct interface.
4. Ensure the fiber optic cable is securely inserted into the new harness.

The right diagram illustrates how to connect with fiber optic cables by unplugging the 2P fiber optic harness from the original car CD and inserting it into the Linux system harness.

4.3. Wired CarPlay/Android Auto Connection

For wired CarPlay or Android Auto functionality, connect your smartphone to the unit using the USB1 port. USB2 is designated for storage devices.

This image presents two diagrams. The top diagram shows the connection for wired CarPlay/Android Auto, specifying that USB1 is for data link and USB2 is for storage link, and CarPlay/Android Auto should use USB1. The bottom diagram provides a troubleshooting tip for distorted sound (noise) in CarPlay or Android Auto, suggesting to connect with AB.

4.4. AMI/AUX Connection

Directly insert the AMI cable if applicable. If not, use the original AUX connection, typically found in the manual gear position or passenger side storage box. For NTG5.0 dual Bluetooth channels, ensure AUX auto switching settings are turned off to separate sound and picture.

This image displays close-ups of an AMI port and a USB AUX port. It provides instructions for connecting AMI directly or, if not confirmed, inserting the original AUX (in the manual gear position or passenger side storage box). It also mentions turning off AUX auto switching settings for NTG5.0 dual Bluetooth channel.

5. Operating the System

5.1. Dual System Switching

The unit supports a dual-system operation, allowing a one-click switch between the integrated Linux system and your original car's NTG system. This ensures you retain all original functionalities while gaining access to the new features.

This image illustrates the seamless one-click switching capability between the original car's NTG 4.5 system and the new Linux system, providing flexibility in user interface and features.

5.2. Wireless CarPlay and Android Auto

The system supports both wireless and wired Apple CarPlay and Android Auto. Once connected, you can access navigation, phone contacts, email, notifications, music, and voice assistants like Siri or Google Voice Assistant directly from the screen.

5.3. Display Technology and Visuals

The 12.3-inch HD (1920x720) IN-CELL screen utilizes full lamination technology to minimize air gaps between layers, resulting in a more transparent display and enhanced visual effects. This technology also reduces light reflection by 75%, improving clarity and reducing glare.

This comparison image shows 'Other' screens on the left, which may cause visual obstruction, versus 'Ours' on the right, which provides a larger field of view for safer driving. It also highlights the difference between an ordinary screen and an in-cell screen, noting that ordinary screens can be dusty, gray, and reflective, while in-cell screens are dustproof, bright, and reduce light reflectivity by 75%.

This image compares the physical design of the Uckazy screen with other products. It highlights the Uckazy screen's narrow bezel (1cm) and lightweight, beautiful body, contrasting it with older products that have wider bezels (1.5cm-1.8cm) and a heavier, outdated design. The Uckazy screen features 1920x720 IPS resolution and reduced light reflection by 75% due to full lamination.

5.4. Automatic Day and Night Mode

The system features automatic light sensitivity, adjusting the display's brightness and color scheme between day and night modes based on your car's original headlights and ambient light conditions. This ensures optimal visibility and reduces eye strain during different driving conditions.

This image illustrates the automatic light sensitivity feature. The left side shows the screen in day mode with bright sunlight, while the right side shows the screen in night mode with darker conditions, indicating automatic adjustment for optimal visibility.

5.5. Original System Integration

• Original car radio and amplifier functions
• Factory steering wheel controls
• Original car mouse knob (iDrive control)
• Display of speed, fuel level, oil pressure, and safety warnings

This image collage demonstrates the system's compatibility with various original OEM features. It shows support for steering wheel controls, OEM reversing camera and parking radar, iDrive control, sound output from the original car stereo, retention of the original CD player, and integration with the original car system.

5.6. Built-in DSP with 16 EQ Segments

The integrated Digital Signal Processor (DSP) features 16 EQ segments, allowing for detailed audio customization. You can utilize various tuning methods and EQ presets to achieve optimal sound quality. This feature enables precise adjustment of speaker positioning and sound balance (front, rear, left, right) to suit personal preferences, enhancing the overall audio experience.
