How to Install the Radio in a Toyota Matrix

The Toyota Matrix was first released in 2003 as a hatchback alternative to the Corolla sedan. Upgrading the factory stereo in a Matrix is a straightforward process that you can complete in minimal time without the assistance of a professional installer. To install an after-market stereo you will need a dash adapter, because after-market stereos are much smaller than the Matrix's factory stereo.

Things You'll Need

• Socket wrench and 10mm socket
• Flat head screwdriver
• Dash adapter

Instructions

1. Disconnect the negative battery cable from your Matrix's battery.

2. Pry the trim panel surrounding the factory stereo away from the dashboard. Slide a flat head screwdriver behind the panel and press out to unlock the retaining clips holding the trim panel in place.

3. Remove the four 10mm bolts holding the factory stereo in place. Slide the stereo out of the dashboard and disconnect the wiring harness and antenna cable from the back of the stereo.

4. Slide the cage included with your after-market stereo into the dash adapter. Slide the stereo into the cage. Connect the wires from the dashboard to the back of your stereo. All after-market stereos have slightly different installation instructions, so refer to the owner's manual accompanying your stereo for proper connection instructions.

5. Slide the dash adapter and stereo assembly into the dashboard. Like the stereo, all dash adapters have slightly different installation instructions. Refer to the instruction sheet included with your adapter to make the proper installation. Use the previously removed 10mm bolts to mount the adapter in place.

6. Replace the trim panel and reconnect the negative battery cable.

Tips & Warnings

• Failing to disconnect the negative battery cable can short out your stereo.
