CX-5 Navigation SD Card
This page covers only what’s specific to the CX-5. Map updates, card cloning, VIN-locking, region codes, and slow-load fixes work the same across every Gen 6 car — see Navigation SD cards & map updates and nav SD performance for the full platform reference.
SD card slot location
Section titled “SD card slot location”The navigation SD card slot is inside the center armrest compartment. On KF cars (2017 onward) it sits on the front wall of the compartment, near the USB ports. On the first-gen KE (2016 and earlier) it may be on the side wall instead.
The slot takes a full-size SD card. Don’t force a microSD adapter if it won’t seat cleanly.
Which CX-5 trims came with navigation
Section titled “Which CX-5 trims came with navigation”| Model year | Trim | Factory navigation |
|---|---|---|
| 2016 (KE) | Grand Touring | Yes |
| 2017–2018 (KF) | Grand Touring | Yes |
| 2019–2020 (KF) | Signature, Grand Touring Reserve | Yes |
| All years | Sport, Touring | No |
A trim that didn’t ship with navigation won’t gain it by dropping in an SD card. The navigation application has to be present in the CMU, and on non-nav cars it isn’t. The slot may exist either way — that’s just the housing, not the software.
The 2021 model year is Gen 7 (a different CMU). Nothing on this page applies to it; see 2021+ CX-5 infotainment.
CX-5-specific quirks
Section titled “CX-5-specific quirks”- Self-ejecting card. The armrest slot uses a push-push spring that wears out on higher-mileage CX-5s. The card backs out, the unit throws “No SD card,” and you lose the map until you reseat it. A folded sliver of tape on the card’s leading edge holds it without blocking the contacts.
- Vibration unseating. Same symptom, gentler cause — washboard roads can walk a loose card partway out. Push until it clicks; if it won’t hold, it’s the spring.
Free updates and replacements
Section titled “Free updates and replacements”Current cards include three years of free map updates through the Mazda Update Toolbox; after that updates are paid (roughly $85–140 per region). Updates are region-locked to the card’s original region.
If your card is missing, a dealer can order a replacement by VIN — see the dealer visit guide. The card pairs to the vehicle after about 100 km of driving, so a used card from another CX-5 won’t work unless a dealer re-codes it. A sector-by-sector clone of your own card is a valid backup in the same car.
