OK, look at my First Post in this thread, down the bottom it tells you what to do in red.
I will message you with what to do now.

I have seen too many people brick CMU by doing to direct latest 74 firmware from 59 or below.
Mazda USA recommends the TWO File update process if below 55, Mazda Europe is below 59.

I recommend ANYONE on or Below 59.00.XXXX to do the TWO File update Process, YES it takes longer but I have never had anyone brick their CMU provided they follow Genuine Mazda .Pdf instructions to the letter, and READ all the WARNINGS included in the link....what to do is all there in link provided to you in message.
Excellent, thanks @ASH8 for this info...

Hey Guys,

So my Girlfriends car is having this weird issue where it will only play music out of one speaker and then randoomly have the music cut in to both speakers then go back to just one.

The other issue is that the navigation icon or map icon will say its volume is zero, and when you change it, nothing happens at all, which is odd; if you plug the phone back in and try again, it will do the same thing.

Is this a firmware or software issue?

Her Siri will no longer work either now for two days

It's a 2020 CX3

Note..
VERSIONS (numbers) of Firmware to Now Install as the Policy and Procedure Has Changed!

The FINAL Install Procedure is now Only a 1 (one) File Install...
(For All Mazda Models already with .up Firmware in use)


IF YOUR MAZDA CX-3 has .up FIRMWARE VERSION Number ON or ABOVE
55.00.650A (for NA N or North America) or
the 56.00.100 (for EU N or 4A N) Europe/UK and Australia/NZ and Middle East etc.
or 58.00.310A or any 59.00.502A or 59.00.650A,
or any 70's Firmware like 70.00.021A, 70.00.100A or 70.00.110 or
70.00.150A or 70.00.335C or 70.00.367A or 74.00.230A or 74.00.311A.

THEN YES YOU CAN UPDATE DIRECTLY to 74.00.324A for the LATEST FIRMWARE.

You now NO LONGER Need to also Update with the pair of
70.00.100A Firmware Files First Before updating to the FINAL 74.00.xxxx.

This is now a SINGLE FILE (1) ONLY INSTALLATION for
YOUR REGION or COUNTRY,


MUST USE EITHER ONE of...

NA N_74.00.324A-UPDATE.UP (North America ONLY)
or
EU N_74.00.324A -UPDATE.UP (Europe/UK)
or
4A N_74.00.311A-UPDATE.UP (ADR, AU. NZ, ME, Asia) (the 74.00.324A for 4A N is NOT AVAILABLE Yet)

THIS IS THE LATEST GENUINE FIRMWARE CURRENTLY AVAILABLE
FROM MAZDA JAPAN As Of December 30th, 2022.

Hi, just making my first post.
I’m studying to upgrade my firmware from 59.00.502 EU N to the newer one finally to be able to upgrade CMU with CarPlay.
ASH8 you are doing a great job, thanks.
As per the previous message multiple updates are no longer required if I understood all correctly, that makes the life a little bit easier 👍
