Are those updates over the air, or do you need to take it to a dealer to apply them?

They're done over USB. The system will look for specially named firmware files (*.up) and auto-apply.

This forum: http://mazda3revolution.com/forums/2014-mazda-3-skyactiv-aud... has some excellent info, and someone usually posts the new FW files. I've done an upgrade and the hacks myself.

Nice. Not quite as convenient as Tesla, but it's great that they give you the ability to do it yourself.

It looks like OTA updates will be available in the future, but who knows if 'older' models will get that feature.
