- Attach Mounting Brackets: If your aftermarket radio requires mounting brackets, attach them to the sides of your new single DIN radio using the screws provided with the radio.
- Integrate Radio into Dash Kit: Slide the aftermarket single DIN radio into the Metra 99-9303 dash kit trim panel. Ensure it sits flush and is securely fastened. Some aftermarket radios may require a separate mounting sleeve or cage to be installed into the dash kit first.
- Wiring Connections: Connect the aftermarket radio's wiring harness to the vehicle's wiring harness using an appropriate wiring adapter (sold separately). Ensure all connections are correct (power, ground, speaker wires, accessory, illumination, etc.). Connect the antenna adapter if needed.
- Test Functionality: Before fully reassembling the dash, reconnect the vehicle's battery and briefly test the aftermarket radio's basic functions (power on/off, sound, radio reception).
- Secure Radio Assembly: Carefully slide the assembled radio and Metra dash kit into the dashboard opening. Secure it using the factory mounting points or any provided with the kit. Ensure a snug fit.
- Reinstall Trim Panels: Reattach all removed trim panels, ensuring they snap or screw back into place correctly.
- Reconnect Battery: Reconnect the negative battery terminal.
Important Note: Some users have reported that this trim kit primarily serves aesthetic purposes and may not provide structural support for the aftermarket head unit. Additional mounting solutions or modifications might be necessary to securely bolt the radio in place. Ensure your aftermarket radio is firmly secured to prevent movement.
5. Operating (Post-Installation Checks)
After completing the installation, perform the following checks:
- Power On: Turn on the vehicle's ignition and power on the aftermarket radio.
- Audio Test: Verify that audio plays correctly through all speakers.
- Radio Reception: Check AM/FM radio reception.
- Basic Functions: Test volume control, station tuning, and other primary functions of your new radio.
- Vehicle Controls: Ensure no other vehicle functions (e.g., climate control, steering wheel controls if an interface was used) have been adversely affected.
6. Maintenance
The Metra 99-9303 installation kit requires minimal maintenance.
- Cleaning: Use a soft, damp cloth to wipe the surface of the dash kit. Avoid abrasive cleaners or solvents that could damage the finish.
- Inspection: Periodically check that the radio and dash kit remain securely seated in the dashboard.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Aftermarket radio does not power on. | Incorrect wiring (power, ground, accessory). Blown fuse. Disconnected battery. | Check all wiring connections. Verify vehicle fuses and radio fuse. Ensure battery is reconnected. |
| No sound from speakers. | Speaker wires incorrectly connected. Amplifier not powering on (if applicable). Radio settings. | Verify speaker wire connections. Check radio's audio settings. |
| Dash kit does not fit flush or securely. | Improper installation of radio into kit. Kit not fully seated. Vehicle variations. | Ensure the aftermarket radio is correctly mounted within the kit. Double-check that the kit is fully engaged with the dashboard clips/screws. Some minor gaps may occur due to manufacturing tolerances or vehicle wear. |
| Aftermarket radio feels loose in the dash. | Insufficient mounting support from the kit. | This kit is primarily a trim piece. Ensure your aftermarket radio is secured using its own mounting cage or brackets to the vehicle's internal structure, not solely relying on the trim kit for support. Additional custom fabrication or brackets may be required for a completely rigid installation. |
