Hi All

I'm looking help to get my hands on an older version of firmware so that I can install AIO without all the messing about with serial connections etc ...

My firmware is V53 so if i go to V56 It should be an improvement and be a straightforward AIO install


Thanks for your help

Firmware (FW) 56 for region NA (North America) is not available in the wild, but FW 55 is (inofficially). Link to old NA FW.
Read the PDF in that folder for the FW update instructions. All on your own risk (new CMU is about 1000 USD). Mazda did not intend users to update - thats why instructions are written for dealers only. Read the PDF before the update and stick to it to the word.

Another way to go:
  • Install FW 55
  • Install ID7/Autorun Tweak from AIO
  • Install FW 59.00.545 NA if you want to install AIO Android Auto Tweak OR install FW 70.00.100, if you do not want to install AIO Android Auto Tweak.
  • That way you still can install tweaks via USB, dont have to do serial access and benefit from a newer FW (less bugs)
