Another Firmware Update question

2017 Mazda CX-5 GS
I’m getting conflicting information, and need a definitive answer. I have a 2017 CX 5 GS, right now running v. 59.00.502. I've seen information that says I can go straight to a one file, actually I have on a USB drive, and other instructions say I have to first do the 2 file 70.00.100A, then the

The latter is what I had intended to do. I have the 2 file update on one drive, and the newer version on another drive, all ready to go.

So, the question is, do I need to do the 70.00.100 before updateing to the latest version?

thank you

never mind - The answer is yes, I do have to do both installations. Mods can delete this if you like.

good luck. The hardware install is very easy, just takes time. I did it on my 2018 few years back.
Its worth it.
