You can copy a Subaru navigation card by connecting it to a computer and using file-copying software, or by taking it to a Subaru dealership to have them create a duplicate

A Subaru navigation card is a removable memory card that stores map data for your vehicle's built-in navigation system. If you want a backup copy or need to transfer the card's contents to another card, you have two main routes: do it yourself with a computer and card reader, or have a Subaru dealership handle it for you. The dealership route is simpler but costs money; the DIY route is free but requires a bit of technical setup.

Before you start, understand that Subaru navigation cards are proprietary — they're designed to work only with Subaru vehicles. Copying the card's data to your computer is straightforward, but the copied data will only work if you put it back onto a compatible Subaru navigation card or use it in another Subaru with the same navigation system generation.

Key Takeaways

  • You can copy a navigation card yourself using a USB card reader connected to a computer, then copy the files to a new blank card of the same type.
  • Subaru dealerships can create a duplicate card for you, which takes a few days and involves a service fee.
  • The card's data is tied to Subaru's proprietary format, so copies only work in compatible Subaru vehicles.
  • Before copying, confirm your card type and capacity — Subaru has used different card formats across model years.

Copying the card yourself with a computer

To copy the card yourself, you'll need a USB card reader (available at electronics retailers for $10 to $30), a computer with a USB port, and a blank navigation card of the same type and capacity as your original. First, insert your original navigation card into the card reader and plug the reader into your computer. The card should appear as a removable drive or folder in your file explorer (on Windows) or Finder (on Mac).

Open the card's folder and select all files — use Ctrl+A on Windows or Command+A on Mac. Copy the files (Ctrl+C or Command+C), then eject the original card safely. Insert the blank card into the reader, open its folder, and paste the files (Ctrl+V or Command+V). Wait for the copy process to finish — this can take several minutes depending on the card's capacity. Once complete, eject the new card and test it in your Subaru to confirm it works.

The key risk here is using the wrong type of blank card. Subaru navigation cards come in different formats depending on your vehicle's model year and navigation system version. Check your owner's manual or contact a Subaru dealership to confirm whether your vehicle uses an SD card, microSD card, or a proprietary Subaru card format before you buy a blank card.

Having a Subaru dealership create a copy

A Subaru dealership can copy your navigation card for you, which removes the guesswork about card compatibility. Bring your original card to the service department and ask them to create a duplicate. The dealership will charge a service fee — this varies by location and dealership, typically ranging from $50 to $150, though you should call ahead to confirm the exact cost.

The process usually takes three to seven business days because the dealership may need to order a blank card or schedule time with their service technician. Some dealerships can do it faster if they have blank cards in stock. Ask when you drop off the card whether they can give you a timeline, and confirm whether you need to leave your vehicle or just the card itself.

Understanding what you're copying

A Subaru navigation card contains map data, road information, and point-of-interest databases that your vehicle's navigation system reads. When you copy the card, you're copying all of this data as a set of files. The copied card functions identically to the original — it has the same maps, the same search capabilities, and the same update history.

However, the card is locked to Subaru's proprietary system. You cannot use a copied navigation card in a non-Subaru vehicle, and you cannot use it in a Subaru with a different generation of navigation hardware. If you try to use a copied card in an incompatible vehicle, the navigation system straightforward won't recognize it.

Updating a copied navigation card

If you copy your navigation card and later update the original card with new map data (through a Subaru dealership or online update service), the copied card will not automatically update. You'll need to copy the updated card again to keep both versions current. This is why many people keep a copied card as a backup rather than as their primary card — the backup stays frozen at the copy date while the original gets updated.

Some Subaru owners copy their card specifically to preserve an older version of the maps in case they need to reference historical data or prefer the older interface. If that's your goal, store the copied card in a safe place away from heat and moisture, just as you would the original.

Troubleshooting a copy that doesn't work

If you copy a navigation card and it doesn't work in your Subaru, the most common cause is using the wrong type of blank card. Before trying again, verify the exact card type your vehicle uses — check your owner's manual under "Navigation System" or call your Subaru dealership with your vehicle's year, make, and model.

A second common issue is incomplete file copying. If the copy process was interrupted — for example, if you unplugged the card reader before the files finished transferring — the card may appear to work but will have missing data. Always wait for the copy process to show as complete and for your computer to confirm the transfer before ejecting the card.

If the copied card still doesn't work after you've confirmed the card type and completed a full copy, take both the original and copied card to a Subaru dealership. They can test both cards in a diagnostic system and tell you whether the issue is the card itself, the copying process, or your vehicle's navigation hardware.

Frequently Asked Questions

Can I copy a navigation card to a microSD card if my Subaru uses one?

Yes, if your Subaru's navigation system uses a microSD card format, you can copy to a blank microSD card of the same capacity. However, some Subaru models use proprietary card formats that look like SD cards but have Subaru-specific firmware. Always confirm the exact card type with your dealership before buying a blank card.

What happens if I lose my original card after making a copy?

The copied card will work as a replacement in your vehicle. It contains all the same map data and functions as the original. You can use it when ready without any registration or set up — just insert it into your navigation system and it will work.

Can I copy a navigation card from one Subaru to use in a different Subaru?

Only if both vehicles have the same generation of navigation hardware. Older and newer Subaru models use different navigation systems that don't recognize each other's cards. Check your owner's manual or ask a dealership whether your two vehicles are compatible before attempting to copy a card between them.

How long does it take to copy a navigation card on a computer?

Copying typically takes five to fifteen minutes depending on the card's capacity and your computer's speed. Larger capacity cards take longer. Don't interrupt the process — wait for your computer to confirm the transfer is complete before removing the card.

Is there a risk of damaging my original card if I copy it?

No. Reading data from a card doesn't damage it. The only risk is if you physically damage the card during handling or if you use a faulty card reader. Handle the card by its edges, keep it away from moisture and extreme heat, and use a reliable card reader to minimize any risk.
