Setup and Installation
Professional installation is recommended. Always disconnect the vehicle's negative battery terminal before beginning any electrical work.
Required Tools:
- Panel removal tool
- Screwdrivers (Phillips and flat-head)
- Socket wrench set
- Wire cutters/strippers
- Electrical tape or heat shrink tubing
Installation Steps:
- Vehicle Preparation: Disconnect the negative terminal of the vehicle's battery to prevent electrical shorts.
- Remove Factory Radio and Trim: Carefully use a panel removal tool to pry off the factory dash trim surrounding the radio. Locate and remove the screws securing the factory radio. Gently pull out the factory radio and disconnect all wiring harnesses and antenna cables. Refer to your vehicle's service manual for specific trim and radio removal procedures.
- Assemble Dash Kit: Attach the provided mounting brackets from the Metra kit to your new aftermarket double DIN radio. Ensure the radio is centered and flush with the front of the dash kit bezel. Secure the radio to the brackets using the screws provided with the dash kit or your aftermarket radio.
- Wiring Connections: Connect the aftermarket radio's wiring harness to the vehicle's wiring harness using a suitable wiring adapter (sold separately). Ensure all connections are secure and properly insulated. Connect the antenna adapter if required.
- Test Fit: Before fully securing, temporarily connect the new radio's wiring to the vehicle and reconnect the battery. Turn on the vehicle and test the radio's functionality (power, audio, balance, fader, etc.). If everything functions correctly, disconnect the battery again.
- Install New Radio Assembly: Slide the assembled dash kit and aftermarket radio into the dashboard opening. Secure the assembly using the factory screws or clips that held the original radio.
- Reinstall Dash Trim: Carefully reattach the factory dash trim panels, ensuring all clips and fasteners are properly engaged.
- Final Test: Reconnect the negative battery terminal. Turn on the vehicle and perform a comprehensive test of the new radio's functions, including all audio sources, settings, and controls.
Operating
The Metra 95-8721B Dash Kit is a passive component designed to house your aftermarket radio. Its operation is directly tied to the functionality of the installed head unit. Ensure your aftermarket radio is properly installed and functioning according to its own instruction manual.
Maintenance
The dash kit requires minimal maintenance. To clean the surface, use a soft, damp cloth. Avoid abrasive cleaners or solvents, as these can damage the finish. Ensure no liquids enter the openings of the installed radio.
Troubleshooting
If you encounter issues after installation, consider the following:
- Poor Fitment: Double-check that the dash kit components are correctly aligned and all mounting screws are tightened. Ensure no wires are pinched behind the radio or trim panels.
- Gaps Around Radio: Verify that the aftermarket radio is properly seated within the dash kit and that the kit itself is fully engaged with the vehicle's dashboard.
- Radio Not Functioning: This is typically related to the aftermarket radio's wiring or the radio unit itself, not the dash kit. Recheck all electrical connections, fuses, and the radio's power supply. Refer to your aftermarket radio's manual for specific troubleshooting.
- Rattling Noises: Ensure all screws and clips are securely fastened. Loose components within the dash or the radio assembly can cause rattles.
If problems persist, consult a professional car audio installer or contact Metra customer support.
