Mazda3 2015 Firmware Help

MaMaMazda31515 · Dec 11, 2024

Hi all! New user here. Respectfully reaching out for help with a Mazda3 2015 firmware update. Anyone still have firmware download links? Any help would be super appreciated – I couldn't direct message the expert ASH8.

The car was purchased in the USA, made in Mexico, and is on 55.00.753 NA N OS Version.
I believe I need to update to 70.00.100A NA N, or is 70.00.100 NA N (sans the A)? I found myself a bit confused. The goal is to replace the USB port to install one that can support Apple Carplay and update to the latest 74.00.324A firmware.

Thank you in advance!

Correct. 70.00.100 first. There usually is just the "A"-Version. I just once saw the D-Version, but this will not be provided to you I assume. Just read how to contact ASH8:

Hello, folks. It's nice to be able to post here. Are other people just finding time at the end of a busy year to go through their "to-do" lists of non-essential service updates to their vehicles? I look forward to reading what others are doing over the winter break. Happy New Year to all!

Hi

Did you contact ASH8 on this forum as he's amazing and will get you the correct software version and full guide on how to install. I did mine this weekend thanks to ASH8 and it worked perfectly.
Or maybe I'm 4 months late looking at when you posted this.
