The can tool plugs into the OBD port in the drivers footwell. It's basically a cable with a box on the end (looks similar to the box on the end of the jb), and a single button.
On E9x's the CAN tool works in conjunction with your gauges to show you what you're changing. Unfortunately this doesn't work with F30's, so you kinda fly blind. The good news is apparently it's set to auto-delete by default. So ever few minutes it will delete any hidden codes.
The real problem is that you have to trust that it's working. I just leave mine plugged in.
