Why Update Your Subaru Firmware?

Firmware updates are essential for modern vehicles as they offer the following benefits:

  1. Improved System Stability: Updates help reduce glitches in the infotainment and navigation systems.
  2. Enhanced Features: Updates can add new features or improve the usability of existing ones.
  3. Compatibility: Updates ensure compatibility with new technology or devices (such as smartphones).
  4. Bug Fixes: Regular updates fix software bugs that might be affecting performance or user experience.

By keeping the firmware updated, you can enjoy a more reliable and functional system while driving your Subaru.

Preparations Before Starting the Firmware Update

Before diving into the update process, there are a few preparations you should take to avoid issues:

1. Check for Update Availability

Not all Subaru models may require a firmware update at the same time. Check if an update is available for your model:

  • Visit Subaru’s Official Website: Subaru often lists available updates in the “Support” or “Owners” section. Look for software update options for your model.
  • Use the Subaru STARLINK® App: For models compatible with Subaru STARLINK®, the app may notify you when updates are available.

2. Gather Necessary Materials

You’ll likely need a USB drive with at least 8-16 GB of space (depending on the size of the update) to perform the update. Ensure the drive is empty and formatted to FAT32, which is typically required for Subaru systems.

3. Ensure Adequate Battery Power

Firmware updates can take anywhere from a few minutes to over an hour. Make sure your vehicle’s battery is charged or keep the car running during the update to prevent any interruptions.

Step-By-Step Guide to Updating Subaru Firmware

Follow these steps carefully to successfully update the firmware on your Subaru.

Step 1: Download the Update Files

  1. Go to Subaru’s Firmware Update Page: Navigate to the support or firmware update section on the Subaru website.
  2. Enter Vehicle Information: You may need to provide details like your Subaru’s model year, model type, and Vehicle Identification Number (VIN).
  3. Download the Correct Files: After confirming your model’s information, download the appropriate update file. Ensure you save the file in a location where you can easily access it for transfer.

Step 2: Transfer Files to a USB Drive

  1. Insert the USB Drive: Plug the USB drive into your computer.
  2. Format the Drive: Format it to FAT32 if it isn’t already, as Subaru’s system usually requires this format.
  3. Copy the Update File: Locate the downloaded firmware file on your computer and copy it to the USB drive. Avoid placing the file in any folder; it should be saved directly on the root of the USB drive.
  4. Safely Eject the USB: Once the file has been copied, safely eject the USB drive from your computer to prevent any data corruption.

Step 3: Prepare Your Subaru for the Update

  1. Power On the Vehicle: Start your Subaru and let the infotainment system boot up completely.
  2. Ensure Stable Power: Either keep the vehicle running or, if possible, use an external power source to maintain stable power to the system throughout the update process.

Step 4: Insert the USB Drive into the Subaru System

  1. Locate the USB Port: Find the USB port that’s connected to the infotainment system, usually located in the center console or near the display.
  2. Insert the USB Drive: Plug the USB drive containing the update file into the USB port.
  3. Wait for System Detection: The system should automatically detect the update file and prompt you to begin the installation. If it doesn’t, you may need to go into the settings menu and find the “Software Update” option.

Step 5: Start the Update Process

  1. Confirm the Update: The infotainment system will usually display a message confirming the update. Follow the on-screen instructions and select the option to start the update.
  2. Wait for the Update to Complete: Firmware updates can take anywhere from 15 minutes to over an hour, depending on the file size and system requirements. Avoid turning off the vehicle, removing the USB drive, or pressing buttons on the system during this time.

Tips for a Successful Firmware Update

To make the process smooth, keep these tips in mind:

1. Use a Quality USB Drive

A high-quality USB drive helps reduce the risk of corrupted files or interruptions. Cheap or malfunctioning USB drives can cause errors or prevent the update from completing.

2. Don’t Rush the Process

Firmware updates require time to process. Allow your system to work through each phase of the update, even if it appears to be stalled. Abruptly stopping the update can lead to incomplete installation or errors.

3. Follow Manufacturer Instructions

Each Subaru model may have slight variations in its update process, so refer to your owner’s manual or Subaru’s website for any specific steps related to your model.

Troubleshooting Common Issues

If you encounter any issues during the firmware update, here’s how to troubleshoot:

1. System Doesn’t Recognize the USB Drive

  • Reformat the Drive: Ensure that the USB drive is formatted to FAT32 and that the update file is on the root of the drive, not in a folder.
  • Try Another USB Port: Some models have multiple USB ports; try another one if the system fails to detect the drive initially.

2. Update Fails Midway or Freezes

  • Restart the Update Process: In some cases, removing the USB drive, restarting the car, and reinserting the drive can reset the update process.
  • Check for Corrupted Files: Redownload the update file and transfer it again if you suspect corruption.

3. Infotainment System Issues After the Update

If you experience any glitches or malfunctions after completing the update:

  • Perform a System Reset: Sometimes, a system reset can resolve issues following an update.
  • Contact Subaru Support: If problems persist, Subaru customer support or your local dealership can assist you.
