5. Setup and Installation
Follow these general steps for installing the Metra 99-3303 radio mount. Specific vehicle disassembly steps may vary.
- Vehicle Preparation: Disconnect the negative battery terminal of your vehicle.
- Dashboard Disassembly: Carefully remove the factory dash trim panels and any necessary components to access the factory radio. Use a panel removal tool to avoid scratching surfaces.
- Factory Radio Removal: Unbolt and remove the factory radio from the dashboard. Disconnect all wiring harnesses and the antenna cable from the back of the radio.
- Mount Assembly (to Aftermarket Radio): Attach the Metra mounting brackets to your new aftermarket radio using the screws provided with the radio or the Metra kit. Ensure the radio is centered and flush with the front of the brackets.
- Wiring Connections: Connect the Metra wiring harness adapter to your aftermarket radio's wiring harness. Match wire colors (e.g., yellow to yellow for constant power, red to red for accessory power, black to black for ground). Solder or crimp connections for reliability and insulate them properly. Connect the antenna adapter if needed.
- Install Radio and Mount: Slide the assembled aftermarket radio and Metra mount into the vehicle's dash opening. Secure the mount using the factory mounting points or hardware provided.
- Test Connections: Before reassembling the dash, reconnect the vehicle's negative battery terminal. Turn on the vehicle and test the aftermarket radio's functionality (power, audio, balance, fader, radio reception, etc.).
- Dashboard Reassembly: Once all functions are verified, disconnect the battery again. Reinstall all removed dash panels and components in reverse order of removal. Reconnect the battery.
6. Operating
The Metra 99-3303 is a passive mounting solution. Its primary function is to securely house your aftermarket car stereo within the vehicle's dashboard, providing a stable and aesthetically integrated platform. Once installed, the operation of your car audio system will be governed by the features and controls of your aftermarket radio itself. The mount ensures that the radio is held firmly in place and that the dash retains a factory-like appearance.
7. Maintenance
The Metra 99-3303 radio mount requires minimal maintenance:
- Periodically inspect the mounting screws and connections to ensure they remain tight and secure.
- Clean the visible surfaces of the dash kit with a soft, damp cloth. Avoid harsh chemicals that could damage the finish.
- If any part of the mount becomes loose or damaged, address it promptly to prevent rattling or potential damage to the radio.
8. Troubleshooting
Most issues related to an aftermarket radio installation are typically electrical or related to the radio unit itself. However, if you encounter problems that might be related to the mount:
- Loose Fit/Rattling: Ensure all mounting screws are tightened. Verify that the radio is properly seated within the mounting brackets and that the dash bezel is securely clipped into place.
- Gaps Around Radio: Double-check that the radio is pushed fully into the mount and that the dash bezel is correctly aligned and snapped into the dashboard.
- Radio Not Powering On: While often a wiring issue, ensure the radio is fully seated and making proper contact with the wiring harness. Re-check all electrical connections.
For electrical or radio-specific issues, refer to your aftermarket radio's instruction manual or consult a professional.
