Installing your bundle
1. The Body – Consists of the head unit and our custom wiring harness.
You’re going to install this first. See all installation videos below.Â
Sony 8100 Bundle Notes:  Your Sony 8100 bundle will arrive with the screen detached from the body of the bundle. The brand new Metra dash kit now utilizes the 4 factory 10mm bolts to secure the body of your head unit into the dash. You’re one of the first to receive their updated and more secure dash kit! This will slightly change the installation from our video, but if you follow these instructions in conjunction with the Sony 8100 install video, you’ll be all set!Â
- Make all your vehicle connections as noted in the document below. We’ve drawn a red box around the vehicle connectors you’ll be using for your installation, which are 3, 4, 5 & OBD2. Vehicle connectors 1 & 2Â will not be used.
- 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.
You will be using vehicle connectors 3, 4, 5 & OBD2
- Next, secure the backup camera connection harness labeled CAM-TY11 (connect the female side of the CAM TY11 to the factory video harness), Sirius/XM satellite connection (if applicable), AM/FM antenna connection, Sony supplied microphone and the USB retention cable connection.
- DO NOT POWER ON YOUR HEAD-UNIT BEFORE ALL CONNECTIONS ARE MADE. This will cause an error when the PAC module is trying to calibrate to your vehicle
More Install Tips Regarding The Components Of Your Sony Bundle
To secure your backup camera connection, ensure the female side of the backup camera harness labeled CAM TY12 is plugged into the factory video connection. The connectors are keyed, so they’ll only fit their mate.
OBD-2 PlugÂ
- You can find the OBD-2 connection under your steering column just above the brake pedal.Â
- The small end of the OBD-2 plug will connect to a small white plug just down the wiring harness from vehicle connectors 1 through 5.Â
- Remove the current connector first, then plug in the small end of the OBD-2. The OBD-2 plug maintains your reverse signal. This is only applicable to 2010 – 2013 4Runners with their reverse camera in their head unit.Â
**This is not applicable to those with their reverse camera in their rearview mirror.**
When looking at the back of the Sony radio, it is a circular plug on the lower left-hand corner of the rear of the device. This is where you will plug in the antenna you removed from your factory radio, or the antenna adapter already connected to your bundle.
- If you have the antennae adapter, plug the male end into the radio and connect the factory antennae into the connector.
- If you have a 2010 – 2012 4Runner, in some cases you won’t have the item I’ve described above as your factory antenna cable is already circular (doesn’t require an antenna adapter) and simply plugs directly into the back of the Sony radio.
2010 – 2013 4Runner:Â
- If your USB connection is in your glove box, included is a kit to create a front facing USB. Follow this segment of video to create a front facing USB.
2012 – 2019 4Runner with a factory USB location underneath your head unit:
- You will have a Toyota factory USB retention cable connected to the required USB connection on the Sony radio to support Apple CarPlay and Android Auto.
You will need to use the provided Sony mic with our bundle. We’ve included our brand new microphone mount with your kit. See this video regarding how to install it.
Or, you can mount the microphone in our previous suggested location. Watch this regarding how to install: 4Runner mic install
Â
2010 – 2013:Â If you selected “Maintain Sirius/XM” at checkout you’ll receive the SXV300.Â
- The SXV300 tuner will be mounted on the back of your bundle, and plugged into the back of the Sony radio.
- The antenna will be in the parts bag in your box.Â
- You will need to use the provided satellite antenna in the kit. We are not able to retain your factory antenna. The antenna will need to be mounted on the outside of the vehicle for optimal signal.
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.
- Small yellow clips:Â Please use the small yellow tab clips; supplied in the 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 in place better.
- Make sure to connect the hazard button wire before installing the dash kit.
3. The Sony 8100 Screen: The Sony 8100 screen display, supporting pieces and trim.
You’re going to install this last.
1.    Attach the USB cable connected to the front of the body to the USB location on the rear of the Sony 8100 screen.
2.    Place the wire in the provided channel on the rear of the Sony 8100 screen.
3.    Attach the two rear panels to the back of the Sony 8100 screen on each side of the neck of the system. These slide into place from the top down. One has a slot that fits over the USB cable.
4.    Attach/slide the Sony 8100 screen into the body.
5.    After placing the Sony 8100 screen into the body, but before securing the screws in place, test all the functions of the radio before proceeding.Â
6.    After you confirmed that the unit functions correctly, screw in the provided 4 silver screws, securing the Sony 8100 screen to the body (2 on each side of the neck of the Sony 8100). For this step, we recommend you use a magnetic tip Phillips-head screwdriver if you have it, as the two outside screws are set down farther than the other two.Â
7.    Slide the small black cover on the neck of the Sony 8100 toward you to line up the final screw location.
8.    Screw in the one black screw in the middle (in the middle of the neck of the Sony 8100).
9.    You have completed installation of your new Sony Bundle! Congratulations!
Troubleshooting
Using a factory phone cable when making your connection for Apple CarPlay or Android Auto is a MUST. When I say factory, I mean just like the cable that originally came with your phone. It cannot be a cable that you bought from Amazon or from the grocery store – those are only charging cables in most cases, not charging and data cables. Also, remember – phone cables don’t last forever. If you ever have connectivity issues in the future – I’d try to swap your cable for a new one.
Download the Android Auto app from the GooglePlay. If you’re experiencing issues with Android Auto, here is a decent video that walks you through some troubleshooting of Android Auto. The head unit shown in this video is not a Sony, so just focus on the general troubleshooting aspects.Â
You can restore the interface to factory default settings by pressing and holding the programming button on the side of the module until the status LED starts blinking red. Once the LED starts blinking red, release the button. You must release the button while the LED is blinking red in order to perform the reset. Please note, the LED will go through two stages before it starts blinking red. First it will blink green, then amber, then red.
This reset will restore the following settings to their factory defaults:
- SWC Mapping
- Parking Brake Output Settings
- Factory Amplifier Settings
- Real Fade will be reset to on
Dip Switch Settings
If after completing these steps you’re not able to function all your steering wheel controls (answer on specifically), on the PAC module change the dip switches on the side of the module to 1, 2 & 3 as “on” and 4 as “off”. Currently, they are set to the exact opposite of that with 4 as “on” and 1, 2 & 3 as “off” – so you’ll just be reversing them.
