4. Installation Guide
Installation of the Uckazy Android Auto Radio is designed to be plug-and-play. However, careful attention to wiring and connections is crucial for proper functionality, especially regarding the fiber optic cables and power connections.
4.1 Power and Wiring Connections
Refer to the provided wiring diagram and ensure all cables are connected correctly. Pay close attention to the specific interfaces for each connection.
Figure 5: Wire definition and fiber optic connection instructions.
4.2 Fiber Optic Cable Transfer
If your original car system uses fiber optic cables for audio, you must transfer them to the new unit's harness. This step is critical for sound output.
Video 1: Demonstrates how to transfer fiber optic cables from the original car harness to the new unit's power cable to ensure sound functionality.
4.3 AMI and AUX Connections
For audio output, connect the AMI cable directly. If the original AUX input is used (often found in the manual gear position or passenger side storage box), ensure the AUX auto switching setting is turned off in the system settings. For NTG5.0 dual Bluetooth channels, sound and picture may need to be separated.

7.1 No Sound or Distorted Audio
If you experience no sound or distorted audio from CarPlay or Android Auto, ensure the fiber optic cables are correctly transferred (refer to Section 4.2) and the AUX input is properly configured and activated (refer to Section 5.3).
