This product is exclusively for vehicles equipped with genuine in-dash navigation systems. It provides a TV canceler function that allows you to watch TV while driving. It's a built-in type that embeds a switch in the original panel, allowing for discreet installation. It features a genuine-style switch with an LED that clearly indicates the operating status, and a mark that lights up in conjunction with the illumination. Although it is brand new and unused, please refrain from purchasing if you are overly sensitive to such things.
