Why It’s Not Always Obvious
Navigation SD card slots are often deliberately inconspicuous — most manufacturers don’t want the average driver accidentally ejecting the navigation card while looking for a place to plug in a USB drive. The result is that many drivers don’t know where their navigation SD card slot is, even after years of owning the car.
The Most Common SD Card Slot Locations
Across all major brands, there are four primary locations where navigation SD cards are found:
- Glovebox — the most common location on VW Group vehicles (VW, Audi, Skoda, Seat). Usually a slot on the back wall of the glovebox, sometimes under the glovebox lid. Audi often has the slot on the side wall of the glovebox interior.
- Head unit face — common on Ford (SYNC), Toyota, Honda, Hyundai, Kia, Mazda, Renault, and Mitsubishi. A small slot on the front face of the infotainment unit, below or beside the screen.
- Centre console storage — common on Land Rover, Volvo, and some BMW models. The slot is in the centre console cubby, sometimes under a removable tray or behind a cover.
- Behind a panel on the dashboard — less common, but found on some older Mercedes and Peugeot/Citroen models. There may be a small flap or panel near the infotainment unit.

What to Do If You Still Can’t Find It
The most reliable source is your owner’s manual — look for “SD card” or “navigation” in the index. A PDF version of most manuals is available through the manufacturer’s website if you don’t have the paper copy. Your vehicle’s navigation Settings → About screen may also display the card’s status, confirming whether a card is detected — which tells you the slot is active even if you can’t see the card itself.
Is It Definitely an SD Card and Not USB?
Some navigation systems use USB drives rather than SD cards for map storage, though these are less common in European-market vehicles. If you’re looking for a slot and only find USB ports, check whether your system uses USB-based map updates instead. The navigation system’s version screen will typically indicate the map storage type.
