3. Feature Rollouts
Manufacturers sometimes add new features via firmware: customizable map themes, 3D landmarks, upgraded lane guidance visuals, and new languages.
4. Compatibility Changes
If Subaru updates its ecosystem (e.g., smartphone app, cloud services, live traffic), firmware updates ensure your vehicle stays compatible.
5. Better Connectivity
Updates can strengthen Wi-Fi, Bluetooth pairing, and USB device stability, while reducing dropped connections or sync issues.
Addressing How Do I Update Subaru GPS Firmware? is more than just keeping maps current—it’s about unlocking a smoother, richer navigation environment.

- Vehicle Identification Number (VIN): You’ll need this when downloading software from Subaru’s official resource site.
- A Computer: Use a laptop or desktop (Windows or Mac) with internet access.
- USB Flash Drive: At least 8 GB in capacity; format it to FAT32 for compatibility.
- Engine Running: To prevent your vehicle from sleeping mid-update, run the engine or keep the ignition on during installation.
- Stable Location: Park in an enclosed space like your driveway or garage to avoid interruption during firmware transfer.
With those items ready, you’re equipped to begin.
Step-by-Step Guide: Downloading Firmware
Visit Subaru Official Resource
Subaru hosts firmware files on their official navigation update page. Start by navigating there in your browser.
- Enter Your VIN
Use the exact 17-character VIN (found on your window sticker or driver-side door frame). The system checks this to confirm which firmware version your vehicle is eligible to receive. - Find Firmware Section
Firmware files are distinct from map files. Look for wording like “System Software Update” or “Firmware Update.” Read the update notes to understand what changes or fixes are included. - Choose the Correct File
Download the file version designed for your vehicle’s year, region, and hardware package. - Monitor Download Size
Firmware is typically smaller than map data—often hundreds of megabytes, not gigabytes. Keep an eye on your ISP download limit as you go.
Once downloaded, locate the file on your system—it might be a .zip, .pkg, or similar container.
Preparing the USB Drive
For smooth firmware installation, your USB drive must be ready:
- Format as FAT32
Windows Users: Right-click on the drive under File Explorer → Format → FAT32
Mac Users: Open Disk Utility → Erase → Format: MS-DOS (FAT) - Maintain Root Folder Structure
Do not create subfolders. Copy the update file(s) to the main (root) level of the USB drive. - Safely Eject USB
Use the operating system’s safe removal process to prevent file corruption.
Installing Firmware in Your Subaru
With the file correctly copied to your USB stick:
- Park Safely & Start Engine
Place the vehicle in Park mode, ensure you’re stationary, and have the engine running—some systems require ignition on but not running; consult your manual. - Insert USB Drive
Plug into the USB port, usually found in the center console or dashboard. - Enter Infotainment Settings
On your touchscreen, go to Settings → System → USB Update. Occasionally, it may be labeled “Software Update” or “System Update.” - Initiate Update
Follow prompts: “Check for Update,” then agree to install. The system should detect the file and enter firmware update mode. - Wait Patiently
Let the process run uninterrupted. The screen may go blank or display a progress bar. Stay within the vehicle and avoid turning off the car or removing USB. - System Reboot
Upon completion, the unit reboots itself and usually displays a confirmation message. - Verify Version
Return to System Info in Settings and confirm new firmware version/date.
Once observed, you’re done! Reformat USB if desired or keep it for future updates.
Common Issues and Fixes
No Update Found
Ensure the file is FAT32-compatible and lies in the root folder exactly as provided. Don’t rename or compress it further.
