Sony Bundle Installation Video

Installing your bundle

1. The Body – Consists of the head unit and our custom wiring harness.

You’re going to install this first.

  • Make all your vehicle connections as noted in the document below. Shown below are the vehicle connectors you’ll be using for your installation, which are the 4 factory looking connectors from the Maestro RR module.
  • All the plugs are keyed plugs, which means they only fit their match on the Toyota side. All you’re doing is matching plugs – it may look like a lot of wires but it’s simple.
  • Important Update: Your bundle will arrive with the OBD harness attached to the back of your bundle. It will need to be plugged in to the OBD port under your steering column in order to retain your: backup camera functionality, gauges and more! This is not shown in the video but you will need to complete this step before powering on your head unit.

You Will Be Connecting:

4 Connectors From The Maestro Harness

USB Retention Adapter

Factory Navigation Adapter

Sony Microphone

AM/FM Radio Adapter

Sirius XM Tuner (If Selected)

  • DO NOT POWER ON YOUR HEAD-UNIT BEFORE ALL CONNECTIONS ARE MADE. This will cause an error when the Maestro module is trying to calibrate to your vehicle.

2. The Dash Kit - Your new matte black Tacoma dash kit. 

  • Tacoma Faceplate: In your kit there are two faceplates. One is already attached to your completed bundle, and the other is wrapped in a separate cover in your shipping box. We always attach the larger of the two covers with your completed bundle (as a higher percentage of Tacoma’s use the larger version) but if it’s not the correct size for your truck simply swap the faceplates before installation by unscrewing the 4 faceplate screws that secure it to the side brackets.
