Quick question. Has anyone tried installing a firmware that was for another region? Does it break anything?
I havent tried it personally but there are reports that your radio tuner will no longer work correctly.

The Mazda toolbox program can be used for Map updates, not system updates.
For a good tutorial on managing system updates visit the link below:

That is the most comprehensive set of online directions available.
Essentially you need to download the update.
Go through the process to clear DTC codes.
Load the update to the CMU
Check to make sure the updates took.
You're done.
I am also experiencing the same thing. Any help would be super appreciated!
I followed this step by step, but committed a pair of mistakes and I'm worried if not completing the whole process might affect my Mazda 3 year 2020 operation.
I have the 70.00.100 4A N version and I wanted to upgrade to 70.00.335 4A N, so I downloaded the "cmu150_ADR_70.00.335C_update.up" file and copied it to a 8GB USB stick previously 32 FAT formatted from https://my.hidrive.com/share/hsodpqja.l#$/Mazda_Firmware/4A%20N%20%28ADR%29/70.00.335C%204A%20N%20all%20MAZDAs
My first mistake: I forgot to unpair two bluetooth devices before starting the whole process described at https://my.hidrive.com/share/hsodpqja.l#$/Mazda_Firmware/4A%20N%20%28ADR%29/70.00.335C%204A%20N%20all%20MAZDAs
My second mistake: I didn't get off the car (step 7) but instead stayed inside and I moved something, so the alarm started to beep.
On step 13 (System Update packages search), I received a message that no Update Software was found on the USB stick.
I couldn't finish the process then.
Should I be worried? Step 6 says "internally clear earlier set DTCs in CMU"
Thank you very much in advanced for your prompt response.

I removed the room fuse for 6 minutes and started the whole process again, using a checked USB 32 FAT formatted and verifying the downloaded file (just followed the full, complete instructions) and now I have correctly installed the 70.00.335 firmware on my Mazda 3.
I'm not willing to buy the hardware yet and try to install it, in order to use Iphone Car Play or Android Auto, because it seems very expensive and not so easy to install.
I just wonder if I could download the Mazda Navigation software to a blank SD and make it work.
If memory serves me correctly each SD card is specifically linked to the vehicle.
Peace and blessings,

Just to make sure I understand correctly: if you've been updated to 70.00.335 there is no way to get root back? I tried to connect to the CMU through serial and to trigger a re-install of the same firmware in order to try and follow the steps from the mzdaio website but the CMU can't seem to see the update file.
Hmm. Imma about to do the same, but I think again if I lose my awesome IO tweaks.
So I have a SanDisk Ultra USB 3.0 which is formated as exFAT, and I've uploaded the cmu150_NA_70.00.335C_update.up on there but when I get to step 9 of the firmware update "Connect the prepared USB memory stick to one of the two USB port," the USB stick isn't recognized by my car. Any suggestions?
Ensure the USB Stick is Fat32, and nothing else is on it, or use a different brand USB...
Peace and blessings,

So the CX-9 cannot read USB 3.0 devices, it will only read up to 2.0 I learned this last week when I tried to put all my music on a 3.0 thumb drive to learn it can't even see a 3.0 device
