Issues with new Mazda Update Toolbox being unuseable

[Driver Bear]

Both I and my dealer have been unable to update the maps on my 2024 CX-5 due to problems with the Mazda Update Toolbox. Version 2.0.0 of this has been released recently but still does not provide a satisfactory fix. Mazda EU Assistance have advised that the update works, but that the option to backup the existing map should not be used as it is this that causes the corruption my dealer experienced in December 2025. I have not attempted to do this, instead asking the dealer to advise me when they have confirmed successful updates.

My understanding is that this affects all Mazda models using the new maps provided by "HERE", and that hundreds of customers are without updates.

I have a secondary issue of the SD card not being recognised when inserted into a USB card reader adapter - yet the same SD card is recognised when inserted into a laptop with a built-in card reader (somewhat rare these days) such as my dealer's or the one I borrowed from a friend. This applied with Windows 10 and now Windows 11. Can anyone suggest a fix for this?

According with my own MazdaUpdateGlobal Adv tool box, the update comes from this link

MazdaUpdateGlobalAdv

Uninstall your current tool box and try to download it again. Make sure o choose your correct region before download it. Top right corner of the page.

You made me curious so I checked my own SD Card. When I plugged in the card reader, I've got a message saying there were some errors with my card. Right clicked, repaired the card, first step. Do not format it. Right click on Properties, then go to the Tools tab and click "Check" button.

Once that was done, I opened the MazdaUpdateGlobalAdv tool box, the last version. The message popped up right away that my card is not recognizable. So what do I do: I checked the Windows Security. And right there you should find a message saying that it just blocked your SD card, "Protected memory access blocked". You change the settings for the app ( Mazda tool box app) to allow it to access the protected memory ( the SD card). Once you do that, you can use the SD card with the tool box. By the way, as of right now, there is no update for North America. Last map version is 2025Q2.

So, in conclusion, my conclusion: Mazda software runs just fine. Check your Windows Security settings or your antivirus software settings, most likely it blocks the access to the SD card.
