This is where you get all the information about software update
Link is dead

1) Please check you region and version by following
on your infotainment screen, go to setting, go to system tab, scroll down to "about", scroll down to "Version information", it will tell you your OS version and region code

If it does not show your region code, turn your car off, unplug everthing that is connected to your usb hub (also disconnect your phone if Bluetooth is on) and press start/stop button for 1 TIME ONLY (auxiliary mode), go to FM mode, PRESS MUSIC BUTTON + FAVORITE BUTTON + VOLUME BUTTON AT THE SAME TIME FOR FEW SECONDS
It will bring up the diagnostic test screen and then you need to enter code 53 then press enter, exit it. Now go back to your "Version information", it should tell you the region code as well.

2) Now to update it (updated): the link has been taken down by Mazda unfortunately. You can try to find different link on Mazda 3 forum or contact your local Mazda dealer for the programming

Then go to Mazda Connect Firmware file, Choose your region file, mine is Na N so that is what I picked, PLEASE PLEASE PLEASE READ the firmware alert text to know what you need to download or you will break the whole system if mess up.
For the instruction video, I found this video which is perfect in explaining how to update your software:
   • Mazda Firmware Update - Prep for CarP...  

3) after you have updated your firmware, which is the newest one (70.00.352), follow my video to install the hardware
you can buy it here:

PLEASE JUST DO IT, IT SOUNDS COMPLICATED BUT REALLY EASY IF YOU WANT TO DO IT!
