Sony Installation Video
Installing your bundle
1. The Body - Consists of the head unit, matte or gloss black dash kit and our custom wiring harness.
- 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. Vehicle connectors 1 & 2 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.
- Retaining Clips: Transfer the 3 clips from the top of your factory dash kit to your new Metra dash kit. These will be needed to secure your new bundle.3
You will be using vehicle connectors 3, 4 & 5
- Next, secure the Sirius/XM satellite connection (if applicable), AM/FM antenna connection, Sony supplied microphone and the USB/AUX port (AXUSB35-SKT).
- 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
Our bundle adds a USB/AUX port location under your head unit for connection for Apple CarPlay & Android Auto. Please ensure you plug in the USB plug from the head unit into our USB/AUX port. The AUX will be unused in this application.
You will need to use the provided Sony microphone with our bundle. We also included our Sony Microphone Mount so that you may place the Sony microphone in the headliner console, if you choose. You may also mount the Sony microphone on top of the steering column with the provided double sided tape and mount.
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.
(1) Ensure the 3.5mm black plug on the back of the radio is plugged in to the blue port on the back of the radio labeled “remote” (2) Ensure the Sony system is set correctly to accept preset steering wheel controls from the PAC module by checking the following within the Sony head unit settings. Go to settings -> general -> steering wheel controls and ensure its set to “preset” If those two items above are good to go, complete the following steps in the exact order below. Try these steps while in “preset” steering wheel control (1) Unplug the power plug from the PAC RP4.2 TY11 for at least 5 seconds. The power plug is the plug with the red, black and yellow wires (and only those color wires). (2) Turn on your vehicle and let the system power up. (3) Complete the master reset process (Restore Factory Settings) noted on page 6 of the attached document (4) When the master reset process is complete, perform a simple reset which is accomplished by just pressing and immediately releasing the “reset” button. After you’ve completed the last step, give it about 10 seconds and then test your steering wheel controls. If after these steps, steering wheel controls are still not working you can always set the steering wheel controls yourself via the Sony head unit settings. To accomplish this you’ll go to settings -> general -> steering wheel controls and set them to “custom” – at this point you’ll most likely be presented with a gear icon and once pressed you’ll be able to manually map each button on your steering wheel controls by following the prompts on your head unit.
Restoring Factory Settings
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.
