1. Introduction
The Phonocar 4/628 ISO car radio cable is designed to facilitate the installation of an aftermarket car radio into compatible Nissan vehicles. This cable acts as an adapter, converting the vehicle's specific wiring harness to standard ISO connectors, ensuring a seamless and secure connection for power and speaker signals without the need for cutting or splicing original vehicle wires.
2. Setup and Installation
Proper installation of the Phonocar 4/628 cable is crucial for the correct operation of your car radio. Please follow these steps carefully:
- Safety First: Before beginning any installation, ensure the vehicle's battery is disconnected to prevent electrical shorts or damage to the vehicle's electrical system or the new radio.
- Access Vehicle Wiring: Carefully remove the vehicle's existing car radio or dashboard trim to gain access to the factory wiring harness. Refer to your vehicle's service manual for specific instructions on dashboard disassembly.
- Identify Connectors: Locate the vehicle's factory wiring harness connectors. These are typically multi-pin connectors that provide power, ground, and speaker outputs.
- Connect Adapter: Plug the vehicle-specific end of the Phonocar 4/628 cable into the corresponding factory wiring harness connectors in your Nissan vehicle. Ensure a firm and secure connection.
- Connect to Radio: Connect the ISO standard ends of the Phonocar 4/628 cable to the matching ISO connectors on your aftermarket car radio. These are typically two separate blocks: one for power/ground and one for speakers.
- Test Functionality: Before fully reassembling the dashboard, reconnect the vehicle's battery. Turn on the ignition and test the car radio's basic functions, including power, sound from all speakers, and any other features.
- Secure Wiring: Once confirmed operational, carefully route and secure all cables to prevent pinching or interference. Reassemble the dashboard and trim panels.

3. Operating the Cable
The Phonocar 4/628 cable is a passive adapter and does not require active operation. Once correctly installed, it enables the car radio to receive power and transmit audio signals to the vehicle's speakers. The operation of your car radio will then depend on the specific features and controls of the radio unit itself.
4. Maintenance
The Phonocar 4/628 cable requires minimal maintenance. To ensure longevity and reliable performance:
- Keep Connections Secure: Avoid excessive pulling or bending of the cables, especially near the connectors, as this can loosen connections or damage wires.
- Cleanliness: If the cable is exposed during maintenance, ensure connectors are free from dust, dirt, or moisture. Use a dry, soft cloth for cleaning if necessary.
- Avoid Extreme Conditions: While designed for automotive use, avoid exposing the cable to extreme temperatures or harsh chemicals.
5. Troubleshooting
If you encounter issues after installing your car radio with the Phonocar 4/628 cable, consider the following common problems and solutions:
- No Power to Radio:
- Check that the vehicle's battery is properly reconnected.
- Verify all connections between the Phonocar cable, vehicle harness, and radio are secure.
- Inspect the vehicle's fuse box and the car radio's inline fuse (if present) for blown fuses. Replace if necessary.
- No Sound from Speakers:
- Ensure the speaker wires from the Phonocar cable are correctly connected to the radio's speaker outputs.
- Check the radio's volume and fader/balance settings.
- Confirm that the vehicle's speakers are functioning correctly (e.g., by testing with another audio source if possible).
- Intermittent Operation:
- Loose connections are a common cause. Disconnect and firmly re-seat all connectors.
- Inspect the cable for any visible damage or frayed wires.
- Radio Not Turning Off with Ignition:
- This often indicates an incorrect connection of the accessory (switched) power wire. Consult the radio's wiring diagram and ensure the correct wires are matched.
If problems persist after troubleshooting, it is recommended to consult a professional car audio installer or contact Phonocar customer support.
