Does the 2020 Subaru Impreza Support Software Updates?

Yes, it does. The 2020 Subaru Impreza comes with the STARLINK multimedia system, which can receive software and map updates. Subaru designed this feature for 2019, 2020, and 2021 models of the Impreza.

When you update, you can fix bugs, refresh your navigation maps, and sometimes get small changes to the look and feel of your infotainment system.

There are different types of updates:

Multimedia or infotainment software
Navigation map updates
Engine control and system firmware updates (these need a Subaru service center)

Types of Software Updates Available

1. Multimedia or Infotainment Updates

This includes everything you see on your car’s main screen — the radio, Bluetooth, Apple CarPlay, Android Auto, and menus. These updates can be done over Wi-Fi or by using a USB drive.

2. Navigation Map Updates

If your Impreza has built-in navigation, you can download new maps to make sure your routes are current. Roads change often, so updated maps help you avoid missing new streets or roundabouts.

3. Firmware or ECU Updates

These are deeper system updates that deal with how the car’s main computer works. They may fix problems with sensors, cameras, or warning systems.You usually cannot install these at home — they need to be done at a Subaru dealership.

Step-by-Step Guide: How to Update Your Subaru Impreza 2020 Software

Let’s go through the full process in easy steps.

Before You Start

Before you try to update, check a few things first:

Check your current version.
- Go to the car’s main screen.
- Tap Settings → General → System Information.
- Note down the version number shown there.
Make sure you have power. Keep the car engine running while updating so the battery doesn’t die.
Never do updates in a closed garage.
Get a strong Wi-Fi or a USB drive. You can use a home Wi-Fi network or a good-quality USB drive (16 GB or larger, formatted as FAT32 or exFAT).
Park safely.The car must stay in “Park” during the update.

Method 1: Update via Wi-Fi (Over the Air)

This is the easiest way if you have a stable Wi-Fi connection near your car.

Turn on your car and the infotainment system.
Go to Settings → General → Check for Updates.
Connect your car to your Wi-Fi network.
The system will search for available updates.
If an update is found, tap Download and Install.
Wait until it finishes — this can take 10 to 30 minutes.
When done, restart the infotainment system.

Tip: Do not turn off the engine or disconnect Wi-Fi while it’s updating.

Method 2: Update via USB Drive

If Wi-Fi doesn’t work or the update is too large, you can use a USB drive.

Go to the Subaru Map Update Portal.
Enter your car’s VIN (Vehicle Identification Number) — you’ll find it on the driver’s door frame or your insurance papers.
Download the correct update files for your Impreza.
Plug a USB drive into your computer and copy the update files onto it.
Safely remove the USB drive.
Start your car and insert the USB drive into the Subaru’s USB port.
The screen will detect the update and show instructions.
Follow the prompts to install.
Keep the car running until the update is finished.

After installation, remove the USB drive and restart the system.

Method 3: Dealer Update (for ECU or Major Firmware)

If your car needs a major update, such as for the engine or safety systems, it must be done by a Subaru dealer.

Contact your local Subaru service center and explain you want to check for the latest firmware or ECU updates.
They will scan your vehicle and perform the update with special tools.
This process can take from 30 minutes to a few hours, depending on the update.
Some updates may be covered under warranty.

How to Check If Your Software Is Up to Date

To confirm your system has the newest version:

Go to Settings → General → System Information.
Look at the version name.
For the 2020 Impreza, the latest versions are often labeled REL_UG.22.13.70 or REL_UL.23.13.70.
If your number matches or is higher, you already have the newest software.
If it’s older, follow the steps above to update.

It’s a good idea to check for new updates every 6 months.

Common Problems and How to Fix Them

Sometimes things go wrong during updates. Here’s how to handle common issues.

1. Update Won’t Start

Make sure the car is in Park and the engine is on.
Check your Wi-Fi connection or USB formatting.
Restart the infotainment system and try again.

2. Update Stops or Freezes

This can happen with weak Wi-Fi.
Move closer to your router or try using a USB method instead.

3. USB Drive Not Detected

Use a different USB port.
Re-format the USB drive to FAT32 and copy files again.
Make sure the update files are not inside extra folders.

4. Black Screen After Update

Turn the car off, wait a few minutes, then restart.
If it still doesn’t work, contact a Subaru service center.

5. Navigation Maps Not Updating

Check that your car actually has built-in navigation (some trims don’t).
Make sure you downloaded the correct files for your VIN.
Try re-downloading the update from Subaru’s site.

Tips to Make Updating Easier

Updating your Subaru Impreza doesn’t have to be stressful. Follow these small tips to make the process smoother.

Use a reliable USB drive. Cheap or damaged drives can cause update failures.
Keep the engine running. Never try to update with the ignition only — it might shut off in the middle.Avoid doing it in a closed space. Carbon monoxide can build up; always update outdoors or in an open garage.
Back up your settings. Note down radio stations or Bluetooth devices, just in case they reset after the update.
Update regularly. Check for updates twice a year to keep everything current.
Be patient. Some updates can take 30 minutes to 1 hour — don’t rush it.

Dealer vs DIY: Which Is Better?

Both options have their benefits.

DIY Updates

Perfect for multimedia or navigation map updates.
Free (you just need internet and a USB).
You can do it anytime without booking an appointment.

Dealer Updates

Best for complex system or ECU updates.
They use special diagnostic tools.
They can check for recalls or hidden software problems.

If you only want to refresh your infotainment or maps, you can do it yourself. But if your dashboard shows a warning or a recall message, it’s safer to go to a Subaru service center.

Why Keeping Your Software Updated Matters

Updating your car’s software might seem like a small task, but it makes a big difference. It helps fix bugs, improves sound quality, refreshes the interface, and gives you more stable navigation. You also make sure the car’s safety and connection features are working their best.

It’s also one of the easiest ways to take care of your vehicle without spending extra money. A few minutes of your time can help avoid future problems and make driving smoother.
