An SD Card Error message may be displayed on the infotainment screen if the navigation SD card is improperly ejected from the card slot
The SD card must be ejected correctly, similar to how a flash drive must be ejected properly from a computer, in order to remove the card from the card slot without affecting the performance of the navigation system.
SD Card Ejection Process
- On the infotainment screen, touch the bottom of the Home page near the Notifications indicator (circled number), if available. The number indicates the number of current notifications. If there is not a notifications number shown, touch the center area of the screen, right of the Application Tray.
2. The Notifications page will display showing that an SD card is installed. Touch the Eject symbol.
3. A “Still ejecting SD card…” message will display on the screen. (Fig. 15) The card can be removed from the card slot when the “Safely Ejected” message is displayed.
If the SD card is not ejected properly, the card may not be able to be read by the navigation system the next time the system is used. If anything is being written to the card when it is removed, there is a risk that permanent data corruption may occur.
In some cases, the damage may result in the navigation system not being able to read the card or system response may be slow. It’s also possible that the damage may not be evident immediately and there may be errors to only specific map data, such as the duplication of streets in particular map views. These types of errors would only be seen when driving in an area shown on the map with the affected data.
Depending on the data that is corrupt, the SD Card Error may or may not appear. Data corruption can only be repaired by replacing the SD card.
Diagnosing SD Card Errors
When diagnosing an SD card error message on a navigation system, always verify that the Read/Write switch on the side of the card is in the correct position. If the switch is in the Read-only/locked (down) position, an SD Card Error message may display. The switch needs to be placed in the Write/unlocked position (up towards the card contacts).
In addition, verify that the radio software (USB programming) is up to date and that the SD card has not been swapped from another vehicle. SD cards are VIN specific.
During diagnosis, always check for the latest bulletins and refer to the Service Information document Navigation System Malfunction (and SD Card Errors).

Product Review: 2021 Chevy Silverado SD CardI recently purchased the 2021 Chevy Silverado SD card from Amazon, and I must say, it has been a game-changer for my driving experience. As a proud owner of a Chevy Silverado, I was thrilled to find this SD card that promised to update the navigation system to the latest maps and software.First and foremost, the installation process was incredibly simple and straightforward. All I had to do was insert the SD card into the designated slot in my truck's center console, and the system automatically recognized and initiated the update. Within minutes, my navigation system was up to date, providing me with accurate directions and real-time traffic information. Plus all my speed limit signs, and HUD displays work perfectly.The updated maps are incredibly detailed and precise, ensuring that I never get lost on my journeys. Whether I'm navigating through city streets or exploring remote backroads, the navigation system guides me with confidence, helping me reach my destination efficiently.One of the standout features of this SD card is the inclusion of points of interest (POIs) such as restaurants, gas stations, and attractions. This feature has come in handy numerous times, allowing me to discover new places and find essential amenities while on the road.I also appreciate the regular updates provided by the SD card, ensuring that my navigation system remains current and reliable. With the ever-changing landscape of roads and infrastructure, having access to the latest maps and software gives me peace of mind knowing that I'm always equipped with the most accurate information.Furthermore, the purchase process on Amazon was seamless, with fast shipping and excellent customer service. The SD card arrived promptly and was well-packaged, protecting it from any damage during transit.Overall, I couldn't be happier with my purchase of the 2021 Chevy Silverado SD card from Amazon. It has transformed my driving experience, providing me with confidence, convenience, and peace of mind on every journey. If you're a Chevy Silverado owner looking to enhance your navigation system, I highly recommend investing in this SD card. It's a small investment that delivers significant benefits

The mazda dealer wanted $400 for the same product. It's been working like the OEM the last 2 years with no issues. Plug and play in mazda cx3. Best value on Amazon.

I recently purchased a used 2022 Equinox and the SD card it came with wasn’t registering that it was inserted. I didn’t feel like waiting for an appt at the Chevy dealership to go through my warranty nor paying $150 to Chevy, so I opted for this. It was easy to set up and worked immediately. I haven’t had problems so far and the maps have been accurate. I’ll update if things change.

Buick Enclave 2021. Had error message. Dealership said $535 for a new sd card. I said pass. Thought I’d give this sd card a try. Able to return if it didn’t work. Followed directions, it worked!! My navigation now works and apple play connects again. So VERY HAPPY!!

The purchase of this card has brought to end one of the most frustrating annoyance's I've experienced. I had removed my original card from the SD slot, which we now know renders the old SD card useless and prevents navigation from working in your car. I plugged this new card into the SD slot (read the directions in the description photo first!) and within 30 seconds, I had my navigation system back to the way it should be. Works great! A+++++ seller!

It didn't work on my 2020 Cadillac xt5. My Onstar went out a few months ago so I thought I'd give this a try. I bought this damn car so I could go out of town by myself and not worry about getting lost. All was great until onstar went out. Thought this might fix that issue but it didn't work. It could be my car or it could be the SD Card. I have no idea.

I purchased my 2021 Yukon Denali from Autos of Dallas ( i will NEVER recommend that dealership to anyone, their terrible), and I received the vehicle and would get an error on the dash "SD Card Not Working Properly"...so I ordered this SD Card, and it worked! GPS & Speed Limit worked immediately! If you purchase one of these from GM they quoted me $451.11 !!I am extremely happy with this purchase, and so glad it all worked! FYI- it does NOT come with instructions, once you insert your card it will prompt you on your screen, however, I did insert my SD card while the vehicle was off, and then turned it on after it had been inserted for about 30 seconds.
