my understanding is there are 3 versions available

30, oldest weakest.
50, came with my 2019, old, weak.
70, the very thing we want.

30 and 50 have a " fail safe" version that has to be installed before the actual version can be installed.

the Mazda dealer told me to install all 5, in order, to go from 50 to 70, just to be sure.


yes, the id # of each has lots more digits than just the first two but the only version I care about is whatever long 70 number is current when I am ready to use it.

the fail safe system was dropped for 70 so there is no fs70 to install first.

I am planning to do this installation and I am really interested in it, I already have several sources of information and the USB module.

But what scares me a bit is damaging my SW.
I don't know anyone who already has it installed on their 2016 Scion ia or Toyota Yaris R.

I just need to update from 55.00.753 NA N to 70.00.335 NA

Do any of you know someone who did it successfully?

I did this to my 2017 Yaris iA, following those instructions you showed where you press the three buttons on your console and type in some numbers to start the update.

I went from 55.00.754 NA N to '70.000.100 NA A Failsafe' to '70.000.100 NA A' and finally to 70.000.367.

This changes the branding to Mazda, and the colors to red, but almost everything remains the same, I'm currently running the latest version without any problems. This weekend I hope to install the new USB hub and wiring so I can use Android Auto.
