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.
  • 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 (if applicable), gauges (if applicable) 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:

5 Connectors From The Maestro Harness

2010-2013 4Runner RR

USB Retention Adapter

Factory Navigation Adapter

Sony Microphone

AM/FM Radio Adapter

OBD II Plug

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 Silver or Charcoal Metra 4Runner Dash Cover. 

You’re going to install this second.

  • Transfer your vents, trim pieces, and install the hazard button trim to the dash kit just like in the video below.
  • Small yellow clips: Please use the small yellow tab clips provided with our bundle to attach to the four tabs on the back of our dash kit. They are more robust than the factory clips and hold our bundle more securely.
  • Make sure to connect the hazard button wire before installing the dash kit into your dash, over the body of the bundle.
