hey guys so I got an aftermarket radio.. it won't work

off the ISO harness.. I have one extra plug.. looking up the wiring diagrams and I noticed its for a god damn canbus decoder.. which isn't supplied.

NOW what exactly does that do? DO I need it?? if so where and the hell do I get one.

2014 mazda 3 GX

thanks
