🛠️Tools Needed:

  • 10mm socket
  • Socket extension
  • Ratchet wrench (Manual or powered)
  • Panel removal tool (Plastic preferred)
  • Small phillips head screwdriver (Magnetic tip preferred)

📝Step-by-Step Instructions

Step 1: Disassembling the Dash

  • Remove the Outer Trim Piece:
    • Grab the side of the trim piece and pull straight back to release it from the tabs.
    • Move to the other side and continue pulling until the entire trim piece comes off.
    • Set the trim piece aside.
  • Remove the Four 10mm Bolts:
    • Locate the four 10mm bolts securing the head unit (two on each side).
    • Use a 10mm socket wrench or powered tool to remove the bolts.
    • Hold onto the bolts as you remove them to prevent dropping them.
    • ⚠️Pro Tip: Place the bolts in the cup holder to avoid losing them.
  • Remove the Head Unit:
    • Place a microfiber towel over the shift knob to prevent scratches.
    • Pull the head unit straight out from the dash and rest it on the towel.
  • Disconnect the Factory Head Unit:
    • Unplug all wiring connections from the back of the factory head unit.
    • Press the tabs on each connector and remove the plugs.
  • Set Aside the Factory Head Unit:
    • With all connectors removed, place the factory head unit aside and prepare for the Sony installation.

⚠️Important Note: If there is a small harness bridging the navigation module at the bottom of the head unit to the main head unit, then it will not be used in the installation of the Sony bundle.

Step 2: Installing the Microphone

  • Remove Headliner Console:
    Depending on trim level this may vary slightly.
    • The headliner console is typically held in with pressure clips and can be removed by pulling straight down.
      • It is recommended to use gently pressure with a panel removal tool to pry the headliner console out.
  • Remove Headliner Console Wiring Harness:
      • Unplug harness connector.
  • Remove Foam Insert:
    • Locate microphone port and remove the foam insert.
  • Remove Mounting Ball On Sony Microphone:
    • The small ball can be removed easily by cutting with a pair of side cutters or a utility knife.
  • Install Microphone To Mount:
    • Push the rounded end of the microphone thru upper support of the mount. The rounded end of microphone should be very close to in line with the bottom of the 2 legs on mount. Align the spot where you cut off the ball to be in-line with one of the upper supports. This will make sure the audio openings on the side of the microphone are not obstructed.
  • Install Sony Microphone Mount:
    • Install mount into headliner console.
    • Insert mount (legs & rounded end of microphone facing down) until the clip locks into place.
  • Route Microphone Wire:
    • Run the wire from the headliner console through the headliner toward the rear view mirror.
    • Reinstall the console, ensuring any slack is pulled toward the mirror.
    • Continue routing the wire along the windshield to the driver-side A-pillar.
    • Tuck it behind the A-pillar cover and guide it down to the driver’s floorboard.
    • Finally, run the wire under the dash and connect the 3.5mm jack to the red mic port on the back of the Sony radio chassis.

Step 3: Installing the Chassis

  • Connect the Three Main Vehicle Connectors:
    • Plug the three Maestro harness connectors into their matching plugs from your dash.
      • All plugs are keyed, meaning they will only fit the correct Toyota connector.
  • Connect the USB Adapter Cable:
    • Plug the USB adapter cable into the corresponding port on the back of the radio.
    • If applicable, secure the cable routing to prevent interference with other components.
  • Connect the Navigation Antenna:
    • Attach the navigation antenna adapter from the GPS post on the back of the radio to the white single-pin Toyota connector.
  • Connect the SiriusXM Antenna (If Applicable):
    • Connect the SiriusXM antenna adapter from the SiriusXM tuner to the black single-pin Toyota connector.
  • Connect the AM/FM Antenna:
    • Plug the white rectangular AM/FM antenna adapter into the factory antenna connector.
  • Route & Connect the OBD2 Harness:
    • The OBD2 harness is required in some installations to transmit vehicle data to the head unit. 
    • Run the OBD2 harness down the left side of the dash and connect it to the OBD2 port in the driver’s side footwell.
    • Test the Maestro system by connecting the OBD2 harness to confirm if gauge data is being transmitted.

Step 4: Securing the Chassis

  • Double-Check All Connections:
    • Before proceeding, verify that all wiring connections are secure and properly plugged in.
  • Tuck in the Wiring:
    • Carefully organize and tuck all wires into the dash.
      • There are a lot of wires, but they will fit—take your time to ensure they are neatly routed.
  • Position & Secure the Dash Kit:
    • Line up the dash kit with the mounting points.
    • Secure it using the four factory 10mm bolts.
      • We recommend leaving the bolts slightly loose until you mount the dash kit during final assembly.

Step 5: Testing the Unit

  • Insert the Screen into the Chassis:
    • Place the screen into the chassis of the unit.
    • Power up the unit to verify that everything is working correctly before reassembling the dash.
  • Adjust Screen Position (Optional):
    • Side Screws: Adjust the screen in and out (closer to or further from the dash).
    • Vertical Adjustment: Move the screen up or down.
    • Horizontal Adjustment: Shift the screen left or right.
  • Adjust the screen to your preferred position, but do not secure it yet—this will be completed in Step 7.
  • Power On the Unit:
    • Turn the ignition to accessory power.
    • If the screen does not turn on within 5-10 seconds, press the home button on the left side of the button bar.
  • Initial Setup Menu:
    • After the Sony logo disappears, follow the on-screen prompts:
      • Set the date and time.
      • Turn off demo mode and press confirm.
  • Test Key Functions:
    • Steering Wheel Controls – Ensure all buttons function properly.
    • Backup Camera:
      • With your foot on the brake, shift into reverse to activate the camera.
      • Alternatively, select "Rear Cam" on the screen to manually view the backup camera.
  • Check Audio Functions:
    • AM/FM Radio – Tune to a station and confirm sound is coming from all speakers.
  • Test SiriusXM Tuner (If Applicable)
    • If the SiriusXM tuner is connected, you should receive Channel 1 (SiriusXM Advertisement Channel).
    • To activate or transfer service, contact SiriusXM and provide your tuner ID.
    • Find your tuner ID in one of three locations:
      • Printed on the tuner itself.
      • Displayed on Channel 0 when listening to SiriusXM.
      • Located on the SiriusXM box in your spare parts bag.

Step 6: Reassembling Your Tacoma

  • Reinstall the Dash Panel:
    • Align the dash panel with its original position.
    • Press firmly along the edges to snap it back into place.
  • Adjust the Chassis for Proper Fitment:
    • If necessary, adjust the radio chassis to ensure it fits properly within the dash cover opening.
    • Once aligned, tighten the four 10mm bolts.
      • ⚠️ DO NOT OVERTIGHTEN!

Step 7: Secure Screen to Chassis

  • Gather the Screws:
    • Your kit includes a pack of five screws to secure the screen to the chassis.
    • One screw is different from the others—set it aside for now, as it will be installed last.
  • Install the First Four Screws
    • Using a Phillips head screwdriver, secure the screen to the chassis with the four identical screws:
      • Screw 1: Top left
      • Screw 2: Top right
      • Screw 3: Bottom left
      • Screw 4: Bottom right
  • Install the Final Screw
    • Slide the small black cover up into position.
    • Secure it in place using the fifth (different) screw.

⚠️ Special Note for Manual Transmission:

  • Locate the purple wire with a white stripe on the main harness coming from the back of the Sony radio.
  • Tap this wire into the reverse wire on the 28-pin connector found on the factory plug in your dash.
  • The reverse wire is in Pin Location 2 when viewing the connector from the end without the wires.
    • Refer to the attached diagram for visual guidance.
  • A purple jumper wire is pre-connected to the purple/white wire to simplify installation.
    • A t-tap is included for easy connection.
  • Carefully cut back the protective covering on the wire harness attached to the 28-pin connector.
  • Use the provided t-tap to securely connect the wire from Pin Location 2 to the Sony radio harness.
