Hello everyone. I figured I would post this here so everyone can see what a member of Mazda6Club found out about the Mazda navigation system. There's a very simple way to disable the speed restriction without cutting wires or using the USB break-in.

Sorry if this has been posted before; a quick search didn't pull anything up.

Unfortunately, we haven't cracked the NB1 system yet, but we're working on it. See the original thread with a link to the video here:

Hope this helps!
