I don’t think you need the Failsafe anymore as the software is all together now. A week agoninuodated my CX-5 to the latest software and it was only one file.
I am sure if you google around a bit you will find the EU software. I only have the NA version.
A quick Google and I found this:

Good luck!
I have a 2020 Mazda CX 5, so not sure if the infotainment system is the same. Only ONE USB port can be used for AA and it has to be the one marked with a small phone symbol. For some reason, mine would not connect correctly, the AA would always be greyed out on the head unit… It would still work but I would need to initiate Maps to start the system.
I have since bought a Wireless AA dongle that works better but it is still not 100% functional…
My phone tells me to continue on the screen if the car to accept something except nothing is ever shown on the actual screen in the car.
My 2019 Jeep works much better and faster than my 2020 Mazda when it comes to the entertainment system!
