Hello guys, i bought a mazda Axela 2015 with mzd connect, i have updated to firmware from Japanese to European 70.00.100 and also i have manage to use tweaks with the help of serial connection. The car is great... But my issue is that the frequency is weak and i can't hear clearly the stations.. Any advice what i should I do? What i should buy to repair the issue, or where i can find any hardware if it anything needs changes if its because its a Japanese car?
Please let me know.

The radio tuner in a Japanese spec vehicle will not work correctly on European FM frequency bands. Japan uses it's own FM broadcasting spectrum of 76-95Mhz. The European spectrum is 87.5-108Mhz (with additional support for DAB/DAB+). You'll need to install a correct European variant head unit. It's unlikely a software update alone would correct this since the physical radio tuner hardware is not designed to pick up the higher frequencies.

The radio tuner is actually a seperate unit and not part of the CMU itself. Replacing just that should work.

Thanks will try to search for radio tuner, even if i don't know where to buy hehe

Seems like Mazda would have them, but they'll probably want you to buy the whole system, again.

You need a new tau, I have a post on upgrading to dab radio, that will fix it.

You should buy a new TAU (Tuner Audio Unit) and use additionall adapter between harness and unit for easy connection, because connectors are usually different.
