This system is just a regular piece of plastic with no individual serial or identification number or any indication of passed vehicle use quality tests or electronic device standards. The voltage shows a variable from 12 to 15 V. WOW! If you go to YouTube, many people complain that the device just randomly turns off, performs several resets, and a hiss comes out of the speakers. It's only a matter of time before this thing lights up in the car's dashboard. I just couldn't trust my new Highlander so I immediately sent it back for a full refund.
