Upgrading your 2019 Nissan Sentra’s radio system? This guide provides a comprehensive overview of the necessary components and resources for a successful installation, focusing on the 2019 Nissan Sentra Radio Wiring Diagram. This conversion requires specific parts and technical knowledge.
Essential Components for the Radio Upgrade
This section details the necessary parts for replacing your 2019 Nissan Sentra’s radio system. Gathering these components beforehand will streamline the installation process.
Core Parts
- Nissan Factory Head Unit: Look for part numbers 2591A5UD0A or 2591A5UD0B. This ensures compatibility with your Sentra’s existing systems.
- Wiring Harnesses: You’ll need a 20-pin female harness and a 20-pin male harness, potentially with additional wiring depending on your specific setup. These harnesses connect the new head unit to the car’s electrical system.
- 40-Pin Custom Harness: This specialized harness integrates the new system with the vehicle’s existing wiring.
- USB Connectors: Two Nissan USB connectors are required for the rear of the head unit. You may already have one. Sourcing these from reputable suppliers is recommended.
- Steering Wheel Control Interface: This requires a programmed and soldered Arduino Mega board with a CAN-Bus Shield V2, a breadboard, and resistors. This enables steering wheel control functionality with the new head unit. This component requires advanced technical skills.
Camera Rewiring and Antenna Adapters
-
Camera Rewiring: Relocating the backup camera may be necessary and can be more complex than anticipated. Detailed instructions are crucial for this step. Newer Sentras (2017+) might have a shielded camera wire requiring specific attention. Refer to available resources for guidance.
-
Antenna Adapter: Your Sentra likely uses a non-amplified antenna. An adapter is required to connect the new head unit. Finding this specific adapter can be challenging.
Additional Considerations and Potential Challenges
Beyond the essential parts, consider these points:
Secret Menu Access and Optional Components
-
Secret Menu Access: Accessing the head unit’s secret menu is necessary for configuring the backup camera settings correctly. Research and understanding these settings are vital for optimal camera functionality.
-
Optional Components: Consider a dash mount USB plug for convenient device charging and an amp level to factory amp audio converter if you have a premium sound system.
Known Issues
-
Diagnostic Trouble Codes: The system may report a “Combination Meter Not Working” error. This is due to the system emulating the original meter.
-
Antenna Open Circuit: An open circuit error might appear because the new system doesn’t utilize the factory antenna amplifier.
This comprehensive guide should assist you in understanding the complexities of a 2019 Nissan Sentra radio upgrade. Remember, this process requires technical expertise, and consulting a professional car audio installer is recommended if you lack experience.
