If you're fitting an aftermarket head unit and trying to keep the reversing camera working, this is genuinely worth knowing: Mazda's multimedia system needs to see a video signal from the camera as the system boots up, not simply when reverse gear is selected.

It's also worth knowing about a genuine, real design limitation: unlike some other manufacturers, Mazda's rear parking sensors don't automatically detect a connected trailer and disable themselves — instead requiring a manual switch fitted in the boot that has to be physically flipped every time.
